OK, so maybe it's not a trick. But I recieved a few pucks of glycerine soap (COL Conk, and a kell's) and since they didn't come with a tub of any sort and I really like the tubs from Mamabears soaps I ordered a few empties in my last order from her.
Now comes the trick, I'm currently deployed to Afghanistan. I don't have a microwave to melt the soap in to form it to the tub.
so, I thought to myself "How am I going to melt this soap?" Ding Ding! it's hot as H E double hockey stick outside and the MB tubs have black lids. So, I put them on the roof of shack I live in and melted them nicely in the sun.
Problem solved!
