I love recycling, and making melted rainbow crayons is a really fun way to recycle all those little crayon stubs which I would normally put in the bin. I’ve seen the idea pop up on a few blogs recently and since I was having a tidy up of the craft area and drawing boxes and the weather is miserable today, it seemed like the perfect chance to give it a go.
Its so easy and the kids loved it, I just put the tray of crayon stubs and our craft cake tin down on the table and the girls filled the holes with the bits of crayons. Some of them needed paper taking off or snapping up a little smaller, which were also good jobs for the girls.
I then put the tray in the oven and we stood back a bit and watched them melt. Some of them didn’t seem to be melting so when it looked like the majority were done I took the tray out again. This then gave us a chance to talk about melting and hardening. I asked Amber – if heat makes the crayons melt then what do we need to make them go hard again? She came up with cold and once the tray was cool enough, we put it in the fridge for a few minutes. Then we knocked the new crayons out of the tin and started colouring. They are a really good size and are perfect for little hands, as long crayons can break easily, and the mixture of colours from a rainbow crayon looks great on pictures.
