Nick's experiment is a riot. I suggested he try Lego blocks....

I hope he gives us an update soon, especially after his heat wave. J

I like the above recipe minus the polystyrene. That stuff is the worst litter on the planet. That and cigarette filters :/

I once saw an orchid that was growing in an old tennis shoe.

Cigarette filters work. Tennis shoes, high-heels, boots...
