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

    Thanks! The kids enjoyed making this today in class - used very thin Styrofoam sheets for the boats.
