I wanted to do a plaster of paris project with the kiddies while the adults watched the Superbowl yesterday. But we ended up not having time, so I did it with our kiddies today. Actually a good thing, since it didn't exactly work like I had planned.
We mixed the plaster of paris in a zip lock bag and poured them into 2 molds - a plate to do a hand print and a heart to make a paper weight for Daddy. All went well up to that point. Then we set it on the bench to set up a bit and we tested it at about 5 minutes and it was still too soupy for us to set our rocks and/or make a hand print. Waited another 5 minutes and WOW it got hard all of a sudden. We quickly tried to make a hand print and squish some rocks in the stuff. You can see the results.
I think they had more fun playing with the rocks...
