We've been having lots of fun doing cool science experiments from our Big Bucket of Science that we bought from Steve Spangler Science (http://www.stevespanglerscience.com/product/big-bucket-of-science). We played with Magic Sand which doesn't get wet in water and also with Insta-Snow which is a super absorbent polymer. It's great fun and learning too. I went to put up pictures of this, but blogger seems to think I have no more space for photos unless I pay. Not sure what to do about this.
