also use it in stuff like solar stills to suck out the capture cup ... or drain into my water bag from a transpiration still...

i was going to add a bigger length of larger diamer around it just for doing short run syphons but i still gotta play with it....

I really tried to design it so i could get maximum shelter fast and then spend the rest of my time looking for natural materials and scout for food etc...

oddly some of this stuff i got ideas from bums... i just have a bigger pocket for gear....
i had a little under 100 buck kit i built for some one i need to see if i can rebuild it.

honestly the contest that this came from is rather a cool idea, you get a ton of ideas for your gear and improve your own , and show off lol
