A few days ago SWIM just showed up at my house with a grocery bad containing 3
boxes of instant cool pads. Well he preceded to lecture me a bit about how I should "Go out more often ect". Soon he pulls out the boxes (2 small and 2 slightly bigger)
I took the larger "brand name box (1 more bag so 4 total). Now he grabs a bowl and heads to the kitchen, when my movie is done I went looking for him
, he was staring at 2 piles off powder ( The brand name he explain and I saw was pure white and almost crystaline looking SWIM told me the tanish powder was the exact same as the white chemicly he says (Ammonia Nitrate HCL) he went ahead and put it all together but after he left a few hours later I started to wonder why ass well after a few clicks I had a 2 picks literatly Identical to what I saw.
