Humans are a weird lot. Not content with merely living, we strive to do things that, naturally, we shouldn't be doing. We fly through the air in hangliders, we swim the depths of the ocean in scuba gear, we talk to people on the other side of the planet over the phone and now, we walk on water in a waterball. What will we think of next?

You can enjoy four waterball rides from Aussie Waterballs for only $19. Each ride is eight minutes long and can be shared between four people so it's fun for the whole family.

Waterballing works like this - you get inside a see-through, plastic ball set upon some water and then you try your darnedest to get as far as you can without falling over too much. It's completely dry inside the waterballs so you can enjoy this activity in a tuxedo if you want. The perfect activity to add to a day of fun, grab this fantastic waterballing deal from GrabOne today.
