code o o o o o o o o o o o o o o o o o o o o o o o o o o o   dot pattern for fall slow. code time fall= 6.3 sec

AVERAGE SPEED = 3.9 meters/ 6.03 sec = 0.6467 m/s
this is my slow one, the idea is thing that can catch much air as it can. and i stick paper clip to string that stick to a plate for make a balance around a plate and make a plate is not gonna flip on the way down.

code o o  o     o       o       o        o        o         o  dot pattern for fall fast code time fall= 0.83 sec

AVERAGE SPEED = 3.9 meters/ 0.83 sec = 4.698 m/s
this is my fast one. my idea is sum thing that catch less air and go fast, and i get this idea from the arrow, because of this shape can go through air easily, and another thing is weight at the top make sure that it not gonna flip on the way down
