How about instant shelters (tents), instant shade (patio umbrellas) instant beds (sleeping bags)... you know, you could probably take almost anything designed for convenience and call it an instant something. Folding chair (instant seating), bicycle (instant transportation)...

Im looking for things that are instant, like polaroid cameras, instant mashed potato, instant coffee etc etc.

Preferably things that aren't food/drink as there is probably thousands! but are more along the lines of instant camera etc etc.
