In this clip I put to the test an idea I have for an air pump inside an upside down aquarium.The goal I have and the reason for this little science experiment is that I wish to understand how some of the bottomless aquariums seen on the internet have an ability to run an air pump and air stone inside the upside down tank without changeing the water levels.The idea I came up with is that all a person needs to do is glue a little air pump to the insides of the upside down aquarium.This air pump would supply air to the airstone, but this air would rise up and retun to the trapped air all the time. this would keep the water levels the same with no need for big sucking pumps hidden around the aquarium with their switches to turn on and off.
