Crayola Glow Sand Ball, I seen this in a parents magazine for Fourth of July Ideas and seen it on clearance at Walmart a few weeks ago. I snagged it up and gave it a go, guess what? It glowed! I was a little optimistic seeing the glow bubbles were a fail last time, but this was so much fun! We used Yellow and still have two more colors to do. It provided hours of play for Caleb and I rolling the ball back and forth on our driveway. Caleb's words for it were "It looks like outer space and stars" he was right, very cool.
