Finally did crayon explosion :) now I only have to figure out where/how to hang it!
Step 1: Pick your favorite crayons
Step 2: Peel off the labels (or not)
Step 3: Hot glue crayons on to something (paper,poster board,card board)
Step 4: Turn your blow dryer on as hot as it goes and on desired air flow (depending on how splatted you want it) and aim it at the crayons
Be careful because it gets super messy!
