Their are about 23 students in my class so I figured I would need a lot of crayons to make the hearts so I went on Ebay and ordered a giant Ziploc bag of used crayons instead of having only one of every color in a 64 pack. I peeled each crayon and put them in a container. I also bought a Wilton Silicone Mini Heart Pan on Amazon.
After I finished that I started chopping up the crayons...that was starting to take forever so I just snapped them into pieces by hand.
When I they were small enough I added them to the pan. The directions on Pinterest did not say any specific way to put the chopped up crayons into the pan so I made sure their were some light colors along with dark colors in each just to make it more of a colorful heart. I set the oven to 235 degrees and put them in for 15 minutes to melt.
I suggest putting the silicone pan on a baking sheet just so its easier to take out of the oven and so the melted wax doesn't spill everywhere.
After I took the pan out their were a few tiny pieces of crayon that did not melt fully so I just pushed the piece into the center of the heart and you couldn't even notice! I decided to take the silicone pan off of the baking sheet and placed it on two gel ice packs to help them cool down faster. After about a half hour they were ready to pop out. This was my final result! I plan to add them onto a Valentines Day card.
