Rainbow Crayons
OLD muffin pans
old broken crayons
Preheat oven to 250. Peel paper off crayons. Put 5-10 different colored pieces in each muffin space. Place muffin pan in oven until crayons melt. Let crayons cool over night. Remove from pans and create beautiful rainbow pictures.
You could add sparkles to make it fun too!
If you didn't have old muffin tins you could use muffin liners ( i would double or triple the liners just to make sure it didn't go anywhere!)

We used muffin liners last time and the kids loved that there were scalloped edges on their "crayons". Sparkles are a great idea.
I saw an article online where they used an old juice box to make big crayons. They cut off the top and washed it all out. Poured one colour of melted wax and put it in the fridge to harden. After layering a few colours, you cut away the juice box container and TADA a big boxy crayon easy for the smallest hands to hold.
