This bubble tube belong to a filter I had. I was wondering if I could make the "Super 5minute sponge filter" with it in the middle. I works just the same way as what I was going to make in the middle. Air comes from the smaller tube and creates bubbles in the larger one. There is a hole in the bottum of the large tube so I guess I have to suspend it slightly off the buttom of the fish food bottle so that water can get sucked up it. It is also just the right size...
