In class were making balloon powered cars. They’re due the day before Spring Break. My car is going to be made of the lightest stuff I can find. I am thinking of ideas to make the car out of and decided to ask my viewers for help. I will be awarding whoever makes an idea for the car with a spot on the blogroll. Here’s some tips for ideas. If there is two objects both the same weight, but different sizes, the littler one has more gravity allied to it, therefore making it slower. Also a ballon powered car hypothetically will go farther if you find a way for the air from the ballon to not use the energy all at once.
