I took my supplies out this weekend and mixed it up and it didnt go boom. I was following directions and use 1tsp of aluminum powder per ice pack and mixed it what I thought was plenty. I put it in the container that lunch meat comes in from the store taped the lid on good and hit it with a 5.56. And got nothing. I am wondering if the amount of aluminum power is to blame like will too much or not quite enough affect the results? Or does it need to be shaken more maybe? Well any ideas would help since I have 3 cases of ice packs and want them to blow up!! Thanks.
