Shake Prank

Use this to scare some friends

1 Rumble Motor (can be found in gaming controllers)
2 Wires, long  (only one shown in picture
1 9Volt Battery
any compressible foam
one container (i ended up using a tin can with its top cut off)

School Glue
A Glue Gun (Which i used instead of a Soldering iron)
A Disposable Brush
Scissors

2 Cardboard Squares (of your choice of side)
Tinfoil (the same size as cardboard)

Attach one of the the motor's wires to one of the long wires and the other motor's wire to one of the battery's terminals positive/negative It does not matter. Then attach the other long wire the opposite terminal.

Use the brush to brush the school glue onto the cardboard squares then carefully lay the tinfoil onto the glued cardboard. try to avoid wrinkles. 

Hot glue the two ends of the long wires to one end of the squares on the tin foiled side. Make sure that the wire is touching the tin foil this is very important!

hot glue small pieces of foam (about a quarter inch thick) to corners and center like so. this is to add crushable space between the plates 

Hot Glue the foamed plate to the other plate

Glue battery to the side of container so that it is not in the way of the motor

Finished product! now go scare so friends and co-workers!
