Add glow stick liquid to bottle of bubbles. Perfect for a summer night. So doing this! When I did this I could barely see a glow in the bubbles. Next time I think I will use less of the bubble soap or more glow sticks.
Crayon hot rocks: If you have not done this yet, you need to. Simply warm up the rocks in the oven (I did 220 for 10 minutes), then put them on a stack of newspapers (or something else you don't care if it gets crayon in it). Just remind them it is hot.
