Now before I get comments about how hot stones and children don’t mix, let me state right from the start, this craft requires adult supervision. My son is 4 1/2 years old and yes he knows not to touch things that are hot, but that doesn’t mean I left him alone with this craft. Supervision is a must.
With that out of the way, painted crayon hot rocks are a super cool, colourful craft! When crayons touch the surface of the heated rocks, the wax melts very easily and looks incredibly vibrant. It’s a wee bit addictive!
