Finger Breakin’ Fun
In order to accomplish the daunting task
asked of us, our group has harnessed the
spring energy of rat traps. Unfortunately
for us, rat traps hurt.
Team Better-Than-You
 Matt Bible - Likes brown dogs.
 Jordan Hines - Enjoys chocolate chip
muffins.
 Neal Parikh - Hates long car rides.
 Brian Petree - Enjoys candy corn.
Project Overview
 A ball is dropped onto the first rat trap.
 The ball triggers the other rat traps as it
rolls down.
 The weight goes up every time a rat trap
is triggered.
 Potential energy stored in rat traps raises
the weight.
Problems
 Friction caused by rope touching wood.
 Angles not steep enough to get good velocity
because of height restriction.
 Springs in rat traps wear out after several uses.
 Rolling friction of ball further inhibits velocity.
 Unable to get string to attach to each mouse trap
independently in sequence.
