The boyfriend gifted me this awesome silicone mold that I had been using to freeze coffee for iced coffees, but I prefer my coffee hot and didn't want such a thoughtful gift to go to waste (silicone makes it easy to pop out your crayons and won't burst into flames in your oven!).
You won't be reusing this for food!
Heat your oven to 375° and just throw all your broken bits and pieces in the mold, it doesn't matter that the colors are all mixed up, it's supposed to be wimbly wombly!
I put the mold on a cookie sheet just in case so I wouldn't have to chip off crayon wax from the inside of the oven.
Check on your mold, stirring frequently and adding more crayon bits as they melt and shift into the mold's nooks and crannies.
Make sure they're completely cooled off before popping out the crayons.
And what better way to try out your new crayons than on a Doctor Who coloring and activity book???
***You can also add a dash of glitter to the crayon bits to make your TARDIS more intergalactic!
