I was looking at these Hand Warmers from campmor. Its really strange because just yesterday I was thinking about ordering one and telling my dad about them. then today when im out at the mall they are selling them! these things are amazing. I was skeptical from just looking online but seeing them in person makes me think totally different. you just squeeze the little button inside and move them around then all the liquid inside the little baggie turns into this stuff that looks like ice except they are nice and warm. they are rated to last 30-60 minutes if you keep them close to your body. i was wanting one for emergencies to carry in my coat pocket and I can bring a couple to work. Im not sure how well they would work when its -10F outside but still I think they will be quite handy and their cheap too. the disposable hand warmers that say up to 8 hours of heat is a big lie and are only good for a few hours when its cold outside. I don't know if anyone cares about these but its getting cold out and I thought these things were really neat. the mall was selling them for 10 and my parents bought a couple even after i told them they are 5 bucks online (and i see now 3.99 for 2 or more). I'm going to order about 10 of them, keep the ones i want and sell the others to people at work.
