Quite possibly this is the easiest project EVAH!
I bought the following supplies at Hobby Lobby...the small bag of glycerin was enough to make the 12 soaps.
I used this muffin tin because we don't really like this particular one for food. YOu can use a tin muffin one if you would like....just be sure not to REUSE it for food....it will taste soapy!
You just follow the directions on the back of the glycerin bag...melt 30 seconds...stir melt 30 seconds more. Put the toy in the muffin tin and fill half way with glycerin and then wait for a few minutes before filling the rest of the way. Its supposed to take 30 minutes for them to harden but mine set up even faster than that. Leave for an hour to make sure they are hardened all the way and pop out! It's seriously THAT EASY!
