If you have a bunch of old crayons laying around here is a fun project that adults can do with the kids.
Using Silicon Pans or Silicone ice trays (which are inexpensive around $1.00)
Take out all of your old crayons and start peeling the paper off of them.
This step is one the kids can do and have fun removing all of the paper.
If you are having problems getting the paper off you may want to soak them in water.
A variety of colors work well, start by breaking them up into little pieces and adding different colors in to the molds. Be sure to add a variety of colors in each slot. You can even have the kids sort them out before putting them in the molds.
Next pre-heat the oven to 250 degrees and place the pans inside.
Put them on an old baking pan or use foil in case of run overs. The crayons don't wash out of the pans so be sure to use ones that are only for craft projects.
Bake for around 5 to 10 minutes and continue to check on them regularly. Poke the crayons with a toothpick once they are all the way melted to release the air pockets.
Do not mix them because you want your colors to stay separate.
Once melted pull the molds out of the oven and allow to cool for about 15 minutes or more.
Be careful when removing them so not to spill. The pans are flexible and have some give.
Place the crayon molds in the freezer and allow them to harden. Run the bottom of the molds under hot tap water to soften up the silicone tray and remove them easier.
Now is the fun part roll out some paper and have fun coloring!
