These DIY rainbow crayons are a fun, easy way to upcycle those small, broken crayon pieces! For my kids, a nice, new box of crayons will keep their attention for some time. However, those tiny crayon fragments don’t entertain them much. They tire of those little crayon pieces so easily and so quickly.

Instead of throwing away those crayon shards, it’s pretty easy to make new Rainbow Crayons that are fun and interesting for the kiddos. This project takes maybe 10 minutes in the oven, plus some time for the crayons to harden back up (it proceeds much more quickly in the fridge, obviously.)

I like how the final shape of these is disc-shaped! It’s so unique and makes it easier for babies and toddlers to grip the crayon! Here is the simple tutorial!

DIY Rainbow Crayons

Supplies:

broken crayon pieces

muffin tin (dedicated to craft projects – don’t use this one for food afterward)



Directions:

1. Peel off the paper around the crayons. Break crayons into small pieces and fill muffin tin spaces.















2. Preheat oven to 300 degrees F. Place the broken crayons into the oven until they melt. The time required will vary based on oven specifications, size of crayon pieces, etc. For me, it took just under 10 minutes.3. Once melted, pull out the muffin tin. Let cool to room temperature for a while. Optional: Place the tin in the fridge for an hour or two for the crayons to harden.4. Once completely cool and hardened, pop them out of the mold.Aren’t they fun?It’s such a simple, quick project that is fun for the kids to participate in! And the final crayons with their melted rainbow appearance are kinda spectacular, I think!!Hope you enjoyed this easy kid’s activity!
