Step one entailed my two helpers peeling all the crayon papersoff of the crayons and breaking them into smaller pieces. Next we put the crayons in rainbow order into the jar, carefully dangling the wick into the jar as we piled the crayons in. I tied the top end of the wick onto a pencil to help hold it taut. Then we decided to use the 100+ degree sun to melt the wax.
It took about 5 hours in the hot sun to get it mostly melted. I put it on top of a sheet of tin foil to help hasten the melting. It worked.
We lit it and enjoyed the warm glow and waxy scent for a few minutes before the wick burned out. We relit it and had a few more minutes before it burned out again.
All in all, I think it was an educational experience about solar heat and color combinations. One side of the jar melted the colors into a lovely black goo, while the other just melted the colors into color pools. The kids had a good time and felt that they were doing a good thing recycling the crayons into something useful.
