Hi
I was just wondering how you get this product to work. i am in an advanced chemistery 2 class and i'm supposed to come up with a more sensible way to make hand warmers. and i have to create it in front of the class in a demonstration way. Then i have to come up with a lab that my class can do. I am at all not saying that your product is not the most profit out-putting hand warmer on the market or that it is not thought through a lot more then what i am going to e able to do. but i am supposed to try. So i would like to know your design and ingredients to your product. If you could get these information ack to me in the next week it would greatly be appriciated. Thank You
