This was a great activity for a hot day. Start by finding some treasures you can put at the bottom of your water table. We used some rocks, little cars, small plastic marine life. Add foam soap. I filled the other half of the water table with water so that Cole could rinse off the items as he found them. If your water table isn't divided you could use a bucket of water instead. The best part about this activity is that our table was nice and clean when he got done finding all the treasures.
