So you have hundreds of bits of broken crayons everywhere and the kids are asking for new ones! What to do!? Well you can easily and simply make them some new ones!
Recycling old crayons (sans the wrappers) is a simple way of using those broken bits of crayon that can haunt pencil cases and crayon tubs for years!
Basically the materials you need are:
Broken crayon pieces (remove the paper wrappers)
Muffin Tin / Ice Cube Tray / Silicone moulds in fun shapes such as stars or numbers
Preheat your oven to 250 degrees.
Peel all of the paper labels off of your broken crayons and separate them by shades of colour — keeping oranges and yellows together, blues and greens together, and pinks and reds together. It’s best not to mix all the colours together as they will turn into a mess of colour.
Spray your moulds, muffin tins, etc. with cooking spray. You can use paper muffin liners, you will just have a ridge around your crayons. And don’t use your favorite muffin tins, buy one from a second hand store or use an old one.
Put them in the oven for about 8 min. You will need to remain close by and check in on them periodically because they will melt quickly.
Once your crayons have melted, take them out of the oven carefully, and then take a toothpick and swirl the wax around. Let them cool. Cooling takes a while, so to help the process along, you can put them in the freezer. Just be sure that they are flat so they harden evenly. Once they are hard, pop them out of your moulds! (If you put them in the freezer, they will have condensation on them, so allow them to air dry for a bit.)
You can also use a flat tray and lay the crayons out flat, then after you have removed the tray of melted crayons from oven, allow to harden slightly so you can push a cookie cutter into the wax and make different shapes.
