Good Idea: DIY - Ice Packs using Liquid Soap. Save money on buying ice packs by taking dish soap, pour it into a ziploc bag, then freeze it. The soap doesn't solidify so it molds to the shape you need, it gets colder and stays colder longer.
DIY Ice packs: I tell all my patients this at physical therapy! Homemade Ice packs: 1 part rubbing alcohol to 3 parts water, gets really cold, but never hardens so you can manipulate it. every athlete (or mom) should pin this!
