how do you pump a snow tube w/o ur mouth or machine(manual also)????

Answer 1

A bicycle air pump will do the trick... if youve got a standard valve stem on the tube (most do).

This article has pics down the right side of three different styles... you can find them at your local department or hardware store. http://en.wikipedia.org/wiki/Bicycle_pump

(And if the air stem is NOT standard, you can probably take it to the hardware store, and make an adapter from parts off the shelf)
