I saw a cute idea on Pinterest and I had to try it out for myself.
There were a few things I learned while making these: Using an ice cube mold doesn't work as well as a candy/muffin mold. The ice cube mold melts a little bit and the crayons don't release cleanly from the mold. See pictures below.
I tried using some WD-40 in the ice cube mold, but the results were the same.
Also, it takes quite a while to melt crayons - much longer than the 30-40 seconds that the tutorial on Pinterest said. More like 5-6 MINS. Check on them often to make sure they are melting.
Thirdly: It pays to put the mold into the freezer before you try to remove the crayons. Just let them warm up a tiny bit before you try to remove them or (if you have little details like arms, legs) they will break.
Remove the wrapping from some crayons.
Break crayons into pieces and place in mold.
Melt crayons in molds - Microwave 5-6 mins on High. Check often.
Place molds with melted crayons into freezer for 5-10 mins.
After removing molds from freezer allow crayons to warm up and then remove from molds.
Ta da! Fancy crayons!
Candy mold men. Lots of colors!
