<em>Some scientific questions are:</em>
1. What is the energy stored in the balloon?
Ans: Potential energy (Potential energy is stored in elastic balloon)
2. Which energy is used in balloon-powered car?
Ans: Kinetic energy. (Whenever the balloon escapes the air, potential energy is converted into Kinetic energy)
3. What is the principle involved in balloon powered car?
Ans: Newtons III law.
