Craft Activity: DIY Rainbow Crayons

by | Feb 1, 2021

Here’s a great way to repurpose bits and pieces of crayons. Mommy influencer Hayley Malan shows how melt them down and make something new!

You know those broken and odd crayons lying around? Here’s a way to revive them into something fun and bright.

This is a really fun and easy fine motor activity for your children. It is also something that they can most likely do independently, so it will give you a few minutes to take it easy!


Old crayons, soapy dish water, silicone mould of your choice (we used a heart shaped one), rolling pin.

Step 1: Preheat oven to 180°C.

Step 2: Remove the crayon labels. The easiest way to do so is to fill a bowl with lukewarm water and add dishwashing soap. Drop the crayons in, and in seven minutes, the labels come right off!  

Step 3: If you want rainbow crayons with a combination of colours that mix well together, then break them apart so that you can combine colours in each mould section. To break the crayons, you can add them to a plastic bag (to avoid mess) and smash them down with a rolling pin.

Step 4: Fill the mould with the crayon pieces, as full as possible. Remember this is not baking and the crayons won’t rise, so fill each hole up!

Step 5: Insert the mould into the oven and bake until the crayons are completely melted (takes about 15 minutes).

Step 6: Turn the oven off and let the crayons completely cool before removing them from the oven. Once out the oven, let them cool down further until they are cool enough and easy for the kids to pop out of the mould.
