We headed to Sears to buy a treadmill for Mom yesterday. Max LOVED the 'tractors,' and spent almost 30 minutes climbing all over them. At one point, he said 'I have to move this seat so I can see how it works,' and went right to work figuring it out.
Speaking of being clever, last night we did an experiment, and left a cup of water on the back porch to see what happens when it is FREEZING cold outside. Lo and behold, this morning, we had a puck of solid ice in the cup. Amazing!
