Chop open some (unused) diapers they contain water absorbent gels, for obvious reasons.
From what I understand though is that its using a sodium polyacrylate that becomes more of a crystal/hard.
I dont think it expands 100x like other snow/gel solutions otherwise the child might get a bit of a suprise when there
suddenly crushed?
The ski ring idea is a good idea, although im not so sure if they still operate here during summer. I've also seen those
dry slopes in the UK, but that foam material hits you up for 150usd per square meter then shipping. And about going to the
Northern Hemisphere I'm going to japan in January
cheap flights from Oz and awesome snow, should be great!
thanks for all your help, and if you have any other suggestions i'd like to hear them,
thanks
