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!
Homemade Eco-Friendly Laundry Detergent: I've been making this and using it for over a year now - works great! (I don't use Oxy clean - better for the environment) It's cheaper than normal detergent and its High Efficiency!
