maybe he actually wanted a suggestion? i ask stupid questions on here all the time because its usually just the first thing that pops into my head.
if you still need ideas, if you have a socket wrench, take the smallest attachment you have, and implant it into the cap of a water bottle, and burn a hole in the side of the bottle near the bottom. now fill the wrench attachment with weed, fill the bottle with water, light and unplug the hole and you got a waterfall.
