Once upon a time, I was bought some Kinetic Sand, and I let the children play with it, inside, unsupervised.
It's fairly accurate to say I regretted this; it's definitely more of an outside activity and not one to be undertaken by small children without adequate supervision. I know this now.
Some time later, Spin Master Toys released a Kinetic Rock Crusher Set and I forgot and forgave and gave some to my toddlers to test. Well technically it was for the big one, as it's for age three plus, but the small one - on form as ever - decided that day was not a day for naps so he joined in with the testing.
Kinetic Rock is made from real rock, and it sticks together in the same way as Kinetic Sand. I will attempt to describe it; it feels sticky, but it doesn't stick to your hands, and squishing it together is marvellously satisfying. It moulds a bit like wet sand; but of course it isn't wet. My daughter asked me how it worked, and I took a stab and guessed at magic. One day, she isn't going to believe my BS but I hope by then I'll have Google in my brain.
Anyway, they were obviously excited by the box when it arrived so we opened it up. Cleverly, the box opens out to become a play space.
Included in the Kinetic Rock Crusher kit are a digger and little construction guy, a rock mould, a tamper tool, a crushing machine and a bag of Kinetic Rock.
Now I do suggest that if you get one of these, that you (or your kids, whatever) play with it inside a Tuff Tray or on a hard surface, as the rocks do tend to get into the carpet and cling to your socks - so let me take this opportunity to apologise to my husband for getting a bit overeager and setting it up in the front room.
The Kinetic Rock Crusher can be bought from various toy shops including Amazon.
If you use the affiliate links above to purchase this kit, a small percentage will go towards the running of this site and the running of the children.
I received the Spin Master Kinetic Rock Crushing Kit for free for the purposes of this review but the words are all mine. Follow Spin Master on Twitter or Facebook for more!
