The results were gorgeous! It would make a great ‘grandparent activity’, and was super for a mini craft project in the school holidays. It would be fine for a couple of kids to do together, as they could do a sticker or two each. Perhaps a little messy for a party situation.
This needs a bit of adult supervision; the top layers need peeling off carefully, and you need 4 containers (we used cups) to pour the glittery sand back into.
Having said that, the $20 price is very expensive for the short length of the activity; if you find this on special offer, it's totally worth it.
