Plinko!
An inefficient and entertaining way to
stamp a piece of paper.
The Team

Ryan Bedinghaus, Corinne Davis, Tim Pobst, and Paul Summers
The Device



A lead ball is projected
into a funnel
The ball rolls down a
ramp
A perfectly inelastic
collision pushes the
stamp down
Stored Energy

Projectile Motion


Conservation of Energy


Ball is shot out of the tube into the funnel
Ball rolls down the ramp
Conservation of Momentum

Ball sticks with the stamping mechanism and
knocks it down
Conclusions



This device took us 3 hours to build,
incorporating aspects that would make it
easier to repeat the experiment reliably.
We had a little trouble making the ball and
wood’s collision perfectly inelastic.
Overall it was a very successful project!
