Alright, I've made it outside (on the grill's burner), and my friend's dad walked out and almost immediately smelled the concoction and asked what it was. He gave us a long, uncomfortable, weird look.

BUT, if you have a few hours to spare to air out the kitchen, and you have a few clever ideas about ventilation, I'm sure you can swing it. The smell isn't exactly of cannabis, either - go for it if you're feeling adventurous. Just don't get caught.
