Wow! What a great time we had at science club on Tuesday. We were learning how to cast  thumbs using dental alginate and casting powder.

First we had to mix one cap of dental alginate with water and stir with a tongue depressor.

Next we had to put the mixture into the thumb pot and wait for the mixture to turn from pink to white. Once it had set we could take our thumbs out.

We then had to mix two caps of  casting powder with water and fill the holes left by the thumbs.

We had to wait 10 mins for the mixture to set. 🙂

Adam’s was amazing!
