The tempeh shuttle has landed. Constructed of bulk soybeans and designed for optimal ventilation and efficiency. Basically, the Rhizosporus mold chews its way into a network that, as long as it has air pockets, can be molded into any shape. Tempeh dildos, anyone?
Temperatures taken after 16 hours of culturing. I used the black spore paste, featured below in all its gooky glory. 
Eat your tempeh kids!
