Picture of Pipe Launcher/ Crusher
As a pop can collector there comes a time when the pop cans need to be crushed to save space. A friend always said why do it the easy way when you can do it *** backwards. Not sure what it meant but I'm sure this can be considered the hard way of crushing pop cans. Yet it is very entertaining and the crusher can double as a tennis ball launcher as well. After a hard days of work just load up the tennis balls and have a good launching. Maybe they will fly high enough to go into outer spay. JK the range is like 10-20ft depending on how strong you are at pulling the string back.

OK, the main material is something I have never before heard of but it does exists as I found two of them at a garage sale.
Materials:
one - 2" long PVC Pipe (size depends on the next item)
one - Garage door deceleration dampers (No idea where to get one, Instead you can use a spring a pipe and a cap of some sort to be around the two inch size. It needs to be able to slide inside the 2" PVC Pipe)
one - 2" to 3/4"PVC DWV Reducing Coupling
one - 3 in. x 2 in. PVC DWV Reducing Coupling

Tools:
PVC Cement and Primer
Ducttape
Spray Paint for Plastic
Dremel with bit (opt use a file)
Masking tape (Frog Tape)


Step 2: Remove lip on 2in x 3/4 reducing fitting

The problem I had was that the pipe of the declaration dampers was around 3/4in. It would fit perfectly inside the reducing fitting if the little inside rim was removed. Use a dremel to remove the inside rim of the 3/4 in side. You should then be able to slide the pipe through.

Just hit the cans with a sledgehammer.

This is sooooooooo cool!
