Wind Racers

In Science, my friends and I made a wind racer using sticks, trash bag, and a bamboo stick. 

Distance: 9m

Time: 16s 61

V = ∆d / ∆t

Speed: 0.542 ms

Why did you choose your design?

We chose this design because we knew that the sail will help it move with the help of the wind.

How could you have changed that design to make your racer go faster? 

Shorter sail because I thought it was kinda long.
