If you live in Auckland, weigh less than 90kg and want to give this a try, head to MOTAT this month for some school holiday fun.
We went this morning and the kids loved it. They would have had another go except for the queues. there was also giant balls, water balloon splash, and heaps of sports activities. I made a wee video of the water walking but our internet is having a huge spaz at the moment. Not sure what's up with that one but it's a huge pain.
