Oh darn thought I had something that would make me millions, a rogue pop bottle. Figured I would have people lining up at my door to come and view the bottle

Here is what happened. The tube from the 3 bottles goes into the input stream of a 600gph powerhead. The actual input to the powerhead got blocked with dead leaves, totally blocked, so the powerhead was sucking from the bottles. Seems that only the one bottle had in fact been flattened before being put into use so it was weaker than the others.

Oh well, maybe I will make my millions next time
