Air Resistance

Today we learnt more about air resisitance. We experimented by seeing which shapes moved the fastest through water, that way we could find out which shapes were areodynamic. We discovered an oval shapes is the best and any shapes with flat surfaces will cause more fluid friction and slow our CO2 car down. I wonder how people will design their car now.

Here is a photo with the shapes in order from fastest to slowest.
