April Maker Challenge #21/30 : miniWaterTower

WHAT: you know these little water reservoirs you stick in soil? i think they are called "glass plant watering bulbs". they look like this:yeah. i wanna make something like that. but out of cheap, everyday materials available out of the home. i *sometimes* neglect to water my plants.

OBJECTIVE: make a little water reservoir system that keeps my plants (in the short term) quenched. try and achieve a decent flowrate. hopefully hyrdrostatically pressure sensitive - so it doesnt just keep flooding these bastards.

HOW: science! and household appliances. i have hotglue, some water bottles (and wine bottles) - maybe the use of some cork and plastic tubing might be useful.

APPLICATION: water. my. plants.

April Maker Challenge #13/30 : bubbleboat

WHAT: a tiny boat. that is propelled solely by bubbles! works in lakes AND bathtubs!

OBJECTIVE: exactly as above. it shouldnt sink when it's air reservoir is emptied. make them cheap and easy enough to make a fleet.

HOW: probably a balloon would be in play somehow. it would be really nice if i could manually change the direction of propulsion using a little rudder.

APPLICATION: boats. that make bubbles. there is no useful application other than fun.
