We had water beads donated to our class. We put them on the light table and the kids are fascinated! Here are some of the kids comments: "Why are they wet, what are they made of?" "They must have some water in them or maybe soap." "Look they bounce, water doesn't bounce." "Maybe it does now, look this one bounces." "I love these little balls." "If I break one open we can see what's inside." (After breaking one open) "look it's the same inside as outside, it's wet in here too!" "I think they're made of water."
