Powered Tape Measure
can you help me make an egg car?
okay, i have to make a non-motor driven vehicle that will transport an uncooked on the ground a distance of 8 meters to a finish line without breaking the egg.
i cannot use any of the following:
a.) no electric motor
b.) no battery powered
c.) no rocket motor (including carbon dioxide cartridge)
d.) no ramp or inclined plane
e.) no measuring tape spring-tape device
f.) no pushing or throwing of the vehicle will be allowed
PLEASE HELP ME.....i'm clueless!
it can be mADE OUT OF ANY MATERIAL
You need a source of energy. My first thought was an elastic band, twisted many times, so that on release it would untwist and power your wheels, but you seem to rule that out.
Internal combustion engines use the expansion of a gas, so a chemical reaction that causes a material to expand would fall in the allowed category. You do not even need a chemical reaction: think compressed air. If you can get a small CO2 tank like those used in Paint Ball, you can make it release gas to a thread wheel.
Speaking of which, you can put mass, solid or liquid, at some height and use its downward movement to propel the egg support a small distance, This may be hard because the mass and height cannot be large, and may not meet the energy requirements for a 8 meter dash.
I'd stick with the CO2 container. Hope this helps. Tell me if it does.
