Broken crayons? No problem!

I posted recently on my Facebook page about recycling old, broken crayons and making them useful again, instead of throwing them out.
Here's how I did it!

You need:
Broken crayons with all paper removed.
A silicon tray/mould  such as a muffin tray, ice cube tray, cake pop mould. Please note it must be silicon.
An oven

Preheat the oven to about 150 c
Organise your bits of crayon into colours and fill the moulds with the crayon pieces. You can really play with the colours here, putting them together as a single colour or a rainbow of colours. Be careful not to overfill the moulds!

Put the tray in the oven and set your timer for 5 minutes. You'll need to put it on top of another tray just in case of spills - you don't want wax on the bottom of your oven! You'll also need to stay nearby and keep a close eye on the wax as it melts. It might take a little longer than 5 min, that's just a guide.  As soon as it has melted, take it out of the oven and set it aside to cool.
Please note, the wax will be very hot and will cause burns if spilt. This is definitely not a job for the children!
Once cool, push the crayons out of the moulds, and set the children free with them, to create their masterpieces. Or just play with them, as my 3yr old likes to do!
