Fish Crazy
 
Heh, here is a picture of my fish. They go up and down in the bubble tube. I think I have 25 Fish in a 4 foot 3 inch diameter tube. I never feed them,
  maybe change the water once every few months.  
 It makes a cool night light. Just buy one of those mini toy aquarium, they come with a blue LED, just put it on top of the tube and it lites it up for night time.
	            
 
 my professor and his brother did that in their younger hoodlum days. only i think it was that powder laundry detergent. I've always wanted to do that to the fountain in the middle of campus...
