Kind of hard to phrase a one-sentence question, but here's what I'm trying to do. I fill to the rim a 5 gallon bucket with water. I attach a hose to the bottom of the bucket. I cover the end of the hose and prick a pin-hole in the covering. I aim the hose towards the top of the bucket. The water squirts out of the pin hole at the end of the hose but doesn't quite reach the top of the bucket. Of course, the lower the opening of the hose, the longer the stream of water from the pin-hole. My question: Are there any changes I can make which would increase the pressure so the water from the pinhole squirts up to the top of the bucket. I've tried short hoses, long hoses, 1/2" hoses, 1" hoses -- even replaced the bucket with a huge funnel. The 1" short hose with the funnel got the stream of water within 1" of the top of the bucket. I'm so close yet so far. What else can I do for the stream of water to reach the top of the bucket without adding any outside power source what so ever -- using only natural air pressure?
Re: How can I shoot water to its own height using natural air pressure?
