Fast Beautiful Controllable Soap Boats Sail Long Distance

This book is an Amazon e-book (special format for Kindle book) about complete guide to create model of boat or ship that could sail without burning fuel, no electricity, and no wind blow. The book is also available in Google books. See below video about 3 colorful origami boat sail together, and a fast boat sails in a long water gutter.

Read also about educational submarines toy which can move forward, dive and resurface, like the real one: baking powder submarine and also electric submarine.

More info about ship and submarine science toys which can move like the real ones, can be read in label boat .

Below video shows that boat is very simple, no complicated moving parts inside. It is very easy to made using household materials and can be performed by a 10-year-old child. Watch a video about 3 origami soap boats sail closely in circle.

But the basic principles to support the boat performance is state of the art technology. Therefore, the book can be a good education for children or adults who want to learn about the boat and ship technology.

Some boat designs are tested to find the best performance. This way the reader can analyze, compare, find, and create their own designs, which hopefully would be better. Video below shows how fast this soap boat can sail with relatively heavy origami body.

The boat is using soap as 'fuel'. Some soaps, shampoos, shower gels, detergents have been tested. Although some chemicals such as alcohol, acetone, can also be used, but this book focuses only on benign household materials.

The boat can be used as promotional gifts for children soap and shampoo products. Because it is very cheap to produce, easy to be packed and transported along with the main product (soaps and shampoos).

With plastic paper origami, the boat could be made to have top body to make it looks beautiful like a real boat.

How To Make Science Toys Ship & Submarine: Made Of Household Materials, Battery Powered

This book is a complete guide to build model boat and submarine with electric power, and made of household material such as: polystyrene, drinking straw, rubber band, zinc plate, etc..

Boat and submarine are an application of Archimedes’ principle. This book guides reader to build science toys to learn and practice Archimedes’ principle.

Beside Archimedes’ principle, hydrodynamic (the study of liquids in motion) also become a major consideration to ensure boat and submarine to perform well. Hydrodynamic not only determines boat and submarine body design, it determines also propeller design.

By understanding about Archimedes’ principle and hydrodynamic, the submarine can be set to dive, hover in water, and resurface.

Drinking Straw Submarine In Swimming Pool

Ebook is available for purchase in the Amazon Kindle Store in some countries, with title as below:
"How To Make Science Toys Ship & Submarine: Made Of Household Materials, Battery Powered"


Drinking straw in video has been fitted with electric motor, battery, propeller, wing, and float to make it hover in the water. This science toy looks like a submarine or a torpedo. Because it has a polystyrene 'tower', I think it is more like a submarine than a torpedo.

It is an application of Archimedes' principle. It is not floating on water surface, but it is not sinking. Archimedes' principle: a water submerged object will get upward force equal to the weight of water displaced by the object. By calculating the weight of submarine, and submarine volume equal to the weight of water displaced, to allow submarine to hover in the water.

This science toy submarine is driven by a small direct current (DC)  motor which is powered by a single triple A (AAA) battery.

Kapal Selam Sedotan Minuman Di Kolam Renang
Sedotan dalam video telah dilengkapi dengan motor listrik, baterai, baling-baling, sayap, dan pelampung untuk membuatnya bergerak melayang-layang di dalam air. Mainan sains ini terlihat seperti kapal selam atau torpedo. Karena memiliki 'menara' polystyrene, saya pikir mainan ini lebih mirip kapal selam daripada torpedo.

Ini adalah aplikasi dari prinsip Archimedes. Kapal selam ini tidak mengambang di permukaan air, tapi juga tidak tenggelam. Prinsip Archimedes: benda yang terendam dalam air akan mendapatkan gaya ke atas sama dengan berat air yang dipindahkan oleh benda tersebut. Dengan menghitung berat kapal selam, dan volume kapal selam sama dengan berat air yang dipindahkan, untuk memungkinkan kapal selam agar melayang di dalam air.

Kapal selam mainan sains ini digerakkan oleh motor arus searah (DC) yang kecil dengan daya dari baterai tunggal triple A (AAA).

Swimming Pool Submarine Moves Without Battery

This yellow plastic origami submarine can move vertically (dive and resurface) and also can move forward when tested in swimming pool. It is not touching swimming pool bed, it is hovering for a while before resurface.

This toy submarine was made of household materials such as: plastic sheet, polystyrene, rubber band, 10 mm (M6) nut. It has no battery.

This is a science toy to learn about Archimedes law and hydrodynamic for submarine design.

Underwater view by Olympus TG-860 digital video camera. For easier to access, the movie was compressed by Handbrake software before uploaded.

The second video is in YouTube, it shows submarine dive and resurface for 10x times. The submarine dives deeper and sails a longer distance.

Both movies are a single long take movie. They are not a joined of few movies. Both movies are showing continuous motion of submarine in action.

In this article, we know that a small model of submarine can move up and down in water. The wing helps this model submarine to move forward, as it is moving up and down in water. No propeller is needed to move model submarine forward.  It is plausible to make a real submarine that can move by changing its vertical motion into horizontal motion. This is an idea to reduce energy cost, and also to make submarine move forward quietly. Theoretically, the energy is needed only to compress the air from ballast tanks into the reservoir tank (smaller tank), when submarine dives. When submarine surfaces, the air can go out from reservoir tank by its own pressure to fill up ballast tanks, no need energy.

Kapal Selam Bergerak Di Kolam Renang Tanpa Baterai

Kapal selam dari origami plastik kuning ini dapat bergerak secara vertikal (menyelam dan muncul kembali) dan juga dapat bergerak maju ketika ditest dalam kolam renang. Kapal ini tidak menyentuh dasar kolam renang, kapal ini melayang sebentar sebelum muncul kembali ke permukaan air.

Kapal selam mainan ini dibuat dengan bahan-bahan rumah tangga seperti: lembaran plastik, polystyrene (gabus), karet gelang, mur 10 mm (M6). Kapal ini tidak memiliki baterai.

Kapal ini adalah mainan sains untuk mempelajari hukum Archimedes dan hidrodinamika untuk desain kapal selam.

Pemandangan bawah air direkam dengan kamera video digital Olympus TG-860. Agar lebih mudah diakses, video ini dikompresi dengan perangkat lunak Handbrake sebelum upload.

Video kedua di YouTube, menampilkan kapal selam menyelam dan muncul kembali sebanyak 10x kali. Kapal selam ini menyelam lebih dalam dan berlayar dengan jarak yang lebih jauh.

Kedua video adalah suatu film panjang yang kontinyu. Bukan gabungan dari beberapa film. Kedua video memperlihatkan gerakan kontinyu kapal selam saat beraksi.

Dalam artikel ini, kita tahu bahwa model kecil dari kapal selam bisa bergerak naik dan turun di dalam air. Sayap membantu model kapal selam ini untuk bergerak maju, saat kapal bergerak naik dan turun di dalam air. Tidak ada baling-baling yang dibutuhkan untuk menggerakkan model kapal selam maju. Adalah masuk akal untuk membuat kapal selam nyata yang dapat bergerak maju dengan mengubah gerak vertikal menjadi gerak horizontal. Ini adalah ide untuk mengurangi biaya energi, dan juga untuk membuat kapal selam bergerak maju dengan diam-diam (tidak berbunyi). Secara teoritis, energi yang dibutuhkan hanya untuk memampatkan udara dari tangki ballast ke dalam tangki penampung (yang lebih kecil), ketika kapal selam menyelam. Ketika kapal selam naik ke permukaan air, udara bisa keluar dari tanki penampung dengan tekanannya sendiri untuk mengisi tangki ballast, tidak membutuhkan energi.

Model perahu listrik ini terbuat dari polystyrene (gabus) dan lembaran plastik. Motor dc kecil di suplai dayanya oleh baterai 9 volt. Baling-baling kapal terbuat dari pelat bekas kaleng minuman. Poros baling-baling terbuat dari sedotan plastik. Untuk mencegah kebocoran air ke dalam perahu, poros baling-baling ditutupi dengan selubung (stuffing box). Stuffing box terbuat dari sedotan plastik.

Rata-rata kecepatan di jalur pertama segera setelah start adalah 40,8 centimeter per detik (1,5 kmh = 0,9 mph). Dengan baterai yang lebih bagus dan dengan motor dc berkinerja tinggi, kapal ini potensial untuk mencapai kecepatan maximum yang lebih tinggi.

Jadi jangan buang polystyrene, sedotan plastik, dan kaleng bekas minuman. Anda dapat membuat perahu yang indah dan kencang dengan sisa barang-barang rumah tangga tersebut.

Water Molecule Energy Propels Mini Torpedo

Mini torpedo in video is made by Vicks inhaler tube, it is propelled by different surface tension or Marangoni effect. It looks like a torpedo or a submarine sailing just below water surface.

I am trying to create a mini submarine with baking powder (sodium bicarbonate) that can submerge, then resurface and sail, and then submerge again. The submarine can resurface after submerge, but so far it cannot sail although it is already on water surface. It is hard to control baking powder reaction and propellant reaction with water, and also difficult to control the timing of those reactions to ensure submarine movement.

Baking powder reacts with water and produces carbon dioxide gas, which helps submarine to resurface after submerge. For more detail about baking powder submarine: http://torgo.org/bpsubs/

Molekul Energi Menggerakkan Mini Torpedo


Mini torpedo dalam video yang dibuat dari tabung Vicks inhaler tabung, dan digerakkan oleh tegangan permukaan yang berbeda atau efek Marangoni. Kelihatan seperti torpedo atau kapal selam berlayar tepat di bawah permukaan air.

Saya mencoba untuk membuat kapal selam mini dengan baking powder (sodium bicarbonate) yang dapat menyelam, lalu muncul kembali dan berlayar, dan kemudian menyelamkan lagi. Kapal selam itu bisa muncul kembali sesudah menyelam, tapi sejauh ini tidak dapat berlayar meskipun sudah di permukaan air. Sulit untuk mengontrol reaksi baking powder dan reaksi propelan dengan air, dan juga sulit memastikan saat reaksi tersebut terjadi untuk memastikan gerakan kapal selam.

Baking powder jika terkena air akan bereaksi mengeluarkan gas karbon dioksida, yang membantu kapal selam terapung kembali setelah menyelam. Lebih detail tentang kapal selam baking powder: http://torgo.org/bpsubs/

Big Fast Surface Tension Powered Soap Boat

This colorful model boat runs fast in water channel with 530 centimeters long for one lane (half lap). The boat can take u-turn and almost complete one lap. Average speed for first lane, from start to u-turn, is about 15.5 centimeters per second.

Top speed is 22.9 centimeters per second (22.9 cms = 0.8 kmh = 0.5 mph) at position 96 inches or 244 centimeters at 17th seconds. Although boat has relatively big size with about 6 inches long and 2 grams weight.

Model boat in video can sail without burning fuel, without electric power, and without wind blow. The boat is very simple, nothing moving parts inside the boat to propel it. Boat is sailing by Marangoni effect or also popular as soap boat. Marangoni effect creates a thrust to propel the boat.

This is a soap boat, it uses shampoo as propellant with only 1 (one) droplet of about 3 mm diameter, about 14 millimeters volume of droplet. The propellant is: Cussons Kids Shampoo energize melon.

Boat is designed with a certain form big area for propellant to react with water. Boat also designed with certain front angle to split open propellant polluted water surface, so the boat can sail back to previous location.

The boat and u-turn walls are polished with "Meguiar's MIRROR GLAZE 8" Carnauba wax.

Boat Sails Without: Engine, Electric Motor, Wind Blow

Fast, long distance,yet controllable direction, and even can take u-turn. The self-propelled red boat in video seems to know where to go.

Model boat in video can sail without burning fuel, without electric power, and without wind blow. The boat is very simple, nothing moving parts inside the boat to propel it.

The boat is using surface tension to sail. It is often called Marangoni effect. The effect is named after Italian physicist Carlo Marangoni, it was published in 1865 for his doctoral dissertation at the University of Pavia, as cited from Wikipedia.

The boat sails for about 3 laps, with a total about 33 meters distance, in about 8 minutes 44 seconds.

The boat uses body wash soap as propellant with only 1 (one) droplet of about 3 mm diameter, about 14 millimeters volume of droplet. The propellant is: Johnson's baby top-to-toe-wash.

Boat is designed to have a big area for propellant to react with water. Boat also designed with certain front angle to split open propellant polluted water surface, so the boat can sail back to previous location. Only about 25 liters of water in the gutter, and the boat can sail for 3 laps before stopped as it hits u-turn wall.

If only it is a continuous gutter without u-turn, the boat could sail up to 100 meters in about 30 minutes.

Perahu Berlayar Tanpa: Engine (Mesin Penggerak), Motor Listrik, Tiupan Angin

Kencang, jarak tempuh jauh, namun arah terkendali, dan bahkan dapat berbelok di tikungan U (u-turn, tusuk konde). Perahu merah dalam video dapat bergerak sendiri dan seperti tahu ke mana harus pergi.

Model perahu dalam video diatas dapat berlayar tanpa membakar bahan bakar, tanpa listrik, dan tanpa angin bertiup. Perahu sangat sederhana, tidak ada bagian yang bergerak di dalam perahu untuk menggerakkan perahu.

Perahu menggunakan tegangan permukaan untuk berlayar. Hal ini sering disebut efek Marangoni. Efek ini dinamai dengan nama fisikawan Italia Carlo Marangoni, dalam disertasi doktornya di University of Pavia yang diterbitkan pada tahun 1865, seperti dikutip dari Wikipedia.

Perahu berlayar sejauh sekitar 3 lap, dengan total sekitar jarak 33 meter, di sekitar 8 menit 44 detik.

Perahu menggunakan sabun pembersih tubuh (body wash) sebagai propelan (zat yang menggerakkan) dengan hanya 1 (satu) tetes dengan sekitar 3 mm diameter, sekitar 14 milimeter volume tetesan. Propelan yang digunakan adalah: Johnson's baby top-to-toe wash.

Perahu dirancang untuk memiliki area yang besar agar propelan dapat bereaksi dengan air. Perahu juga dirancang dengan sudut depan tertentu untuk membelah dan mengupas permukaan air yang sudah tercemar propelan, sehingga perahu bisa berlayar kembali ke lokasi sebelumnya. Hanya sekitar 25 liter air di dalam saluran, dan perahu dapat berlayar selama 3 lap sebelum berhenti sesudah menabrak dinding tikungan U.

Jika saja saluran air tersebut memanjang lurus tanpa tikungan U, perahu bisa berlayar hingga 100 meter dalam waktu sekitar 30 menit.

Different Surface Tensions Create Marangoni Effect

This video shows pepper powders are spread on top of red colored water surface at center of a basin. A small amount of dish-washing soap is introduced into the water. Soapy water has lower surface tension then pure water. We can see water flows from lower surface tension to higher surface tension, as pepper powders spread. This phenomena is called Marangoni effect.

Click here , to see Marangoni effect propels a model boat to sail for about 33 meters distance in 8 minutes 44 seconds. That model boat can sail in straight line and even can take u-turn smoothly, just like the boat knows where to go. Shown in below photo the self-propelled red boat is about to take u-turn after sailing for about 520 centimeters or about 17 feet.

The book is also available on Google Play or go to below address:

In below video, water level height is very low, only about 1-2 millimeters. Because of that, we can see lighter red color at the center as water level is lower on that area. Water tends to accumulate at area with higher surface tension. Then the red color back to homogen when no more different surface tension, when no more Marangoni effect.

Diagonal lines inside basin are measuring in centimeters, we can see there are markings for 5, 10, 15, and 20 centimeters. Also there is measuring tape at the bottom. Therefore we can easily estimate current flow for every second.

We are now polluting air by burning fossil fuels. If only the soap will not pollute the water, if only the effect more powerful and more efficient, could it become an alternative energy source?

Some soaps have been tested for propellant, such as:

Perbedaan Tegangan Permukaan Menimbulkan Efek Marangoni

Video ini diatas memperlihatkan bubuk lada tersebar di atas permukaan air berwarna merah di tengah baskom. Sejumlah kecil sabun cuci piring dicampurkan ke dalam air. Air sabun memiliki tegangan permukaan yang lebih rendah dari air murni. Kita bisa melihat air mengalir dari daerah bertegangan permukaan rendah ke daerah bertegangan permukaan yang lebih tinggi, saat serbuk lada menyebar. Fenomena ini disebut efek Marangoni.

Klik disini, untuk melihat efek Marangoni mendorong model perahu sehingga berlayar sejauh sekitar 33 meter dalam waktu 8 menit 44 detik. Model perahu dapat berlayar lurus dan bahkan dapat berbelok di tikungan U, sepertinya perahu tahu ke mana harus pergi. Di foto kedua diatas terlihat perahu merah yang dapat bergerak sendiri sedang berbelok di tikungan U setelah berlayar sejauh sekitar 520 sentimeter atau sekitar 17 kaki.

Lihat video diatas, tinggi muka air sangat rendah, hanya sekitar 1-2 milimeter. Karena itu, kita bisa melihat warna merah terang di tengah saat tinggi air menjadi lebih rendah pada daerah itu. Air cenderung menumpuk di daerah dengan tegangan permukaan yang lebih tinggi. Kemudian warna merah kembali homogen saat tidak ada perbedaan tegangan permukaan, saat tidak ada lagi efek Marangoni.

Garis diagonal di dalam baskom mengukur dalam sentimeter, kita bisa melihat ada tanda-tanda untuk 5, 10, 15, dan 20 sentimeter. Juga ada pita pengukur (meteran) di bagian bawah. Sehingga dapat dengan mudah diperkirakan kecepatan aliran arus untuk setiap detik.

Sekarang kita membakar bahan bakar fosil sehingga membuat polusi udara. Jika saja sabun tidak akan mencemari air, jika saja efek Marangoni lebih kuat dan lebih efisien, bisakah hal ini menjadi sumber energi alternatif?
