Fizzy Moon Sand
After my first attempts at moon sand (http://www.stoppingattwo.co.uk/post/94419116423/moon-sand) I decided to take things further by adding some bicarbonate of soda to it. Because this was bound to get messy I decided that we would do this outside and laid out a tarpaulin on the grass to put the moon sand on. Freyja immediately got stuck in with playing with it again.

After a while I gave her a bottle of lemon juice and suggested that she pour it on to the moon sand. The moon sand fizzed and bubbled as the acid of the vinegar reacted with the bicarbonate of soda. Being a science teacher, this was very pleasing to me and I would have loved to have explained to Freyja about the reaction that was happening. Freyja wasn’t massively bothered about the fizzing, and decided that she would get a stick to stir the mixture.
Pouring in the lemon juice and investigating the fizzing mixture
After she had emptied the entire bottle of lemon juice onto the moon sand I had expected her to have had enough of it, but she was now more interested in it than ever. She carried on stirring it with the stick and then using this to scrape the soggy moon sand into a mould. There was only so much she could manage to do with the stick and I was really surprised to see her get her hands stuck into the sticky mixture. She then discovered that with some squeezing and kneading of the mixture it formed a lovely dough-like consistency. She was delighted to see that she could form an imprint of her hands in the dough too.
She then had so much fun with this, pretending she was cooking with it. She enjoyed making holes in it with the stick, squeezing it into the mould and finally pushing small stones into it.

We only finished the activity when it started to rain and I was going to let Freyja bring in the (now quite dirty) lump of dough into the house. I can’t believe how much she got out of the moon sand and subsequent dough. She is definitely happier with messy play now and considering all I needed to use for this was flour (which I used old stuff which was at the back of the cupboard), baby oil, bicarbonate of soda and lemon juice it was a very cheap activity for the hours of fun that it provided us with.
