Did you know - you could Power a small Paper Boat with Toothpaste????
Yes - that is true, toothpaste has a unique property that it dissolves and expands on contact with water. Using this property of toothpaste, we can make a small paper boat move forward.
Here is how to make it work:
1. Cut small Paper boats
2. Punch a small hole at the bottom
3. Make a small slit to make an opening (watch video)
4. Apply some toothpaste at the bottom of the hole and put it in water
5. Watch it move and have fun
