Try it, just suck in through the mouth using a harden hose and exhale through your nose. Good luck. Or a powered snorkel pump on a float on the surface, know as a hooka, and some dive weights. Terry K Yeh the harden hose is difficult at longer lengths. So is garden hose. Thats why, in my initial post, i recomened a larger diameter hose you see  When I was a kid, we decided to try this at the bottom of a swimming pool. I volunteered to be try breathing with the hose. There were four of us. I went below with the hose, then the other three kids took deep breaths and blew into the hose topside. I was able to extend my bottom time by about 2 minutes, until they got winded and I got dizzy. Well, I'm still hear and probably didn't damage too many brain cells. Damaged them enough to use hear instead of here. |
