What is the easiest way to crush ice to make a slush?

I forgot to mention I don't have a blender.

Without a blender, you will just need some other tool. You can set the blade on a plane to a thick cut and it will shave a block of ice just fine. But if you are starting with ice cubes, then put them in a plastic bag wrapped in a towel on a concrete floor. Smash with a board or a hammer.

Hmm...w/out the use of a blender I guess you could simply crush the ice with a hammer. There are ice shaving machines that you can buy, and this time of the year they aren't especially expensive. I'm not sure about using a food processor or some other type of kitchen counter top appliance.

Well if you don't have a blender then a food processor might work or a machine specially made to maked frozen drinks. But those are more expensive. You can go get a cheap, very cheap blender at Wall Puke for like 20 bucks or some other rediculously low amount.

wrap up your cubes in a tee or kitchen towel, then use a rolling pin or hammer, or anything that you can beat and smash it with, open the towel and you will have crushed ice. some of it will stick to the towel but will shake off.

Electronic blender.

Wrap up a load of ice cubes in a tea towel or plastic bag and smash it up with a rolling pin.
