Giant water beads
XL waterbeads in a variety of colours, these ones grow for days, they form all kinds of weird and wonderfull wrinkles and then strange shapes untill you have GIANT water beads
Photos are day 4, day 2 and when we first put them in water
Crystal soil is a water absorbant polymer, it is NOT to be eaten and should only be used under strict supervision.
Non toxic (but still.... it's polymer, don't eat it)
