I found the ideas for these ice blocks here. They looked like such a fun idea I had to try it with the boys. I did the idea that was recommended by freezing layers so you can have little treasures through out and not just sunk to the bottom.

Well this what the kids saw and needless to say they were a little confused. That is until I told them what the idea was. They needed to melt the ice and get the items out of it. Let the cold wet fun begin.
Sam tried sliding it around to melt it. It worked a little. Not fast enough for them though.
Gabe decided to get his hammer. (I promise that it is just a plastic hammer) This started working better. He was actually chipping away it.
Sam decided that he better get a hammer to. LOL. These boys had tons of fun. It kept them busy for a good hour. They did use other things to melt it down. Both boys decided to keep to Gabe's tools.
When they finished, my crazy little monkey decided to try and drink some of the water. They finished off the whole project by taking a bath to warm up. Touching ice for so long made them a little cold.

This is such a fun idea for a summer activity. Just stick it out side and the kids can see how fast it melts in the sun. The boys are already asking for the next time to do it.
