Experiment Design Analysis - Gummy Launcher

One day you were bored in Mr. Rick's science class. You were supposed to be making graphs, but instead were eating gummy bears when Mr. Rick wasn't looking. At some point you realized that by placing one end of the ruler on the edge of the table with the other end hanging off the edge, you could make a "spring board" that could launch the gummy bear into the air and it would stick to the ceiling. The plastic ruler you had worked OK, but they dropped off the ceiling within 3 minutes. Looking around the room, you trade some gummy bears for what's-her-name's wooden ruler - maybe that will stick the gummy bears better.

Oh snap! Mr. Rick caught you. Hoping to get out of a referral, you decide to use the lab report format to write-up a rough draft of the ruler "experiment" you were doing.
