The Team

The Project Our project goal was to design a Rube- Goldberg device that would stamp a piece of paper We used parts from around the house, as well as recycled materials and store-bought objects Total cost of the device was under $15.00

The Pulverizer

The Sequence 1. A marble is rolled down a series of ramps, and strikes a second marble resting at the end 2. Marble rolls down a track and through a pipe, where it activates a mouse trap 3. Attached to the mouse trap is a spoon, which launches a pebble into a soda bottle 4. The pebble falls through the mouth of the bottle and strikes another marble, which rolls down a ramp and activates a rat trap 5. Attached to the trap is a mallet with a stamp, which swings 180° and strikes the sheet of paper

The Energy Conversions Step 1:Gravitational Potential to Kinetic Energy Step 2:Gravitational Potential to Kinetic Energy Step 3:Spring Potential to Kinetic Energy Step 4:Gravitational Energy to Gravitational Potential Energy Step 5:Gravitational Kinetic to Spring Potential Energy

The Conclusion The construction of the project was tedious and time consuming, and took lots of testing due to the amount of moving parts. The only problems experienced were the trajectory of the mouse trap and getting everything to fall in place. The project was fun and successful!
