Water cartage tank

Zenonie,

Below is what I found on the Rapid Spray site. Is this sort of thing you mean?

I'd say the 2 halves just lock together, and you chuck 'em into the tank.

Hi Bob, that's neat! I don't think ours can make a complete ball like those ones. But we are working on slotting them together to make a ball shaped round thing. They look like they would then all stay apart in the water. Thanks heaps. Cheers Zenonie
