Al has outgrown them for the most part. I've not seen a water experiment in his bathroom for quite awhile. Wait. "Outgrown" isn't the right word....its really more that he's evolved to a new level of experimentation. Last week, I found this in the freezer: It's a rock. Frozen in water. To see if the rock would somehow change by being frozen.
Ironically, the EXACT SAME DAY that I found the rock in the freezer, Craig found this:
It's Gman's Matchbox cars water experiment, found under the dining table. Yes, there is water in there. Craig calls it a Hot Wheels Car Wash. It's even in the EXACT SAME type of cup as Al's frozen rock!
Dear Lord, please give me strength to get thru another 10 years of water experiments.
