Realizing that it may be cruel to keep a new life form imprisoned in your body, and wary of the possibly deleterious effects on the new life of the massive quantities of drugs you are planning to ingest later on, you decide the best course of action is to vomit into a terrarium. You find one in your neighbor's basement.
"I tried to grow shrooms in there but they kept getting contaminated, go ahead and take it," he says.
You head home and dim the lights. You put on a Peter Tosh record backwards and start to retch into the terrarium. After only a few heaves, most of your stomach's contents are transplanted into their new home.
You add a stick and some rocks to complete the effect of a proper terrarium.
