“The Revolting Blob”
Trey Carrier Stephen Phillips Aaron Messer Jordan Davis
Purpose Turn on a lamp shaped like a teddy bear
Overview
Ball is launched using elastic energy down a tube
Overview
Ball proceeds down a ramp with a slight incline towards a pivot
Overview
Ball hits a pivot which in turn hits another ball
Overview
Second ball rolls down another ramp towards a funnel
Overview
Ball goes through the funnel and down another ramp
Flicks a switch
Overview
The lamp turns on as a result of hitting the switch

Conclusions Elastic energy makes a good initial source of energy
Funnels are useful to create straight drops
The bottom of a chopped off funnel covered with duct tape makes a great golf ball holder
Device is pretty inefficient; the velocity of the ball hitting the switch is much smaller than the velocity of the ball being launched due to collisions and friction
