Today we are going to crush ice without a blender place the ice and a heavy-duty freezer bag and burp out the air for demonstration purposes using a floozy sandwich bag take a clean towel hammer and ice outside to a hard flat surface like cement place the ice in between the layers of the towel tap don't bang the hammer against the ice use the long end of the hammer to avoid damaging the cement cracks this is not the time to show off those muscles pick up the top layer the towel slowly the freezer bag may show somewhere but ice pours out of as and bag.
