In Room Two we had experiments on a paper ‘copter that we had to cut
and fold. The first one was when we just let it drop and see how it drops.
It went down roughly. We then did another one and it also went down
roughly. Then we added 3 paper clips to the second one and it went
down perfectly. Lastly we cut half of one of the propellers. It twirled the
whole way down and it went down nice and smooth.
