Doughnut maker Krispy Kreme designed the world's first grass flip flops to relax city workers by giving them their own mini-park to walk around in. I found them here. You can see I've been on a grass kick lately, noticing grass sculptures around the net. I am, for instance, completely enamored with this little grass dress created by a Cornell student. Really cute spring fashion.
Growing grass on a pair of flip flops is easy enough, but I got to wondering how to grow grass on objects with vertical surfaces, like the car in the previous post. I guess it's a case of a little bit of knowledge being a dangerous thing, because I found this a church interior covered in grass along with the explanation of how it was done. You can read the step by step for yourself, but
in a nutshell, the walls are smeared with moist clay, then seeds are pressed into the clay. The wall is watered to keep the clay moist. The whole shebang lasts about 20 days before it starts to deteriorate.
This opens the door to a lot of possibilities in my mind. Nothing on the scale of an entire church, but I have clay and I have grass seed. Maybe a little grass graffiti is in my future. I'll keep you posted.
