4. A Soap Powered Model Boat
For the number 4 no our list of cool experiments to do at home with household items you will need a foam tray, a tray, a bowl, liquid dish soap, and a toothpick.
First, you need to cut the foam tray into a boat shape about 2 inches long. Take the toothpick, dip it in the dish soap and apply the soap onto the sides of the notch at the back of the boat. You’ve made your boat and now carefully place it on the surface of the water and watch it scoop across the water. Soap helps break down the surface tension so there is enough force to push the boat.
