A can crusher is a metal vice you nail to the wall and you set a can in it and pull down a handle that crushes the can flat.It makes things smaller so you can get more in the bag .You get twice as more in a bag if you crush the cans.Some people sell or recycle them.I find it easier to use one and a lot more neater than having so many bags.
