Engaged Hands-on Science For Kids.
Once they’re suitably impressed, train them how the “trick” works by explaining the chemistry of polymers. What when you may make sand that was “afraid” of water? This 5th grade science experiment uses waterproofing spray to create you-gotta-see-it-to-imagine-it hydrophobic sand. Glow sticks are at all times a giant hit with kids, so that they’ll have a terrific time studying in regards to the chemical reactions that make them work.
Then use grape juice to show the message or hold it up to a warmth source. This density demo is a bit more sophisticated, however the effects are spectacular.
