washing machine motor/drill
small, wide pipe(like a paint can but plastic)
1 inch diametre non-sparcking metal balls
rubber belt
wood
screws
drill/screw driver
belt drive (circle of wood with a grove in the edge for the belt to go in, so it wont slip)
First you will have to make the frame out of the wood and the screws. You will then need to screw the motor down on the wooden base. A rubber belt will then be placed around a wooden circle(belt drive) with a groove in it for the belt, the wooden disk will then be placed onto the washing machine motors drive. The belt will then be put around another wooden disk which will then turn a piece of wooden tube. Another piece of circular wooden tube will have another hollow piece of metal tube covered in masking tape over it, placed opposite the first one. The big wide tube you have will be blocked of completely so no powder will be able to get out. Then on the other end you will need to seel it with a plastic screwable blocker, so you will be able to take it on and of to put and take the composition in and out. The wide tube will then be placed onto the two tubes you have. When the motor is turned on, the belt will drive the piece of wood around with the wide tube on it so it will turn around and crush the chemical with the hard lead non-sparking balls.
