The Science

What provides the force to power the rocket car?

Issac Newton’s third law of motion states that action and reaction are equal and opposite. So the force leaving the back of the rocket car is equal to the force that will propel the rocket car forward. Easy!

How is the force generated?

Water and air power - Start to fill a bottle full of any substance and eventually the pressure forces the gas out of the bottle. Think about that shaken bottle of coke when the cap is released! The gas is released along with a good quantity of coke.

The force of the gas and the liquid will propel the bottle in the opposite direction.

The rocket car uses this principle but replaces the carbon dioxide with air and the coke with water.
