    Interesting item. Stones are more like tiny tiles than stones. Tried half a packet. They swell reasonably slowly, so you can watch continuously, or on and off to see the difference. Didn't get quite as large as I expected, and more of a blob effect, rather than a stone. Left them at school to dehydrate so can't say how well this is achieved. Interesting product.

    Was a bit disappointed as I expected them to get larger than they did but the kids loved them which is the main thing!
