Shortly after graduating from college I needed a cheap mattress and bought a camping air mattress (I'm not a fussy sleeper). Unfortunately I didn't realize before purchasing it that the valve is a completely different shape and it's virtually impossible to find an adapter to connect a "regular" bicycle pump ( Schrader valve ) to the air mattress.

I didn't want to spend more money buying a special pump JUST to blow up the mattress, so I did it orally (yah, that sounds slightly obscene)...this was when I discovered that you can make yourself faint by hyperventilating.

There's gotta be a better way. Here it is.

Step 1: Materials

*Plastic valve used for inflating beach balls, swim floats, etc. - you can find these in sports stores or even sports departments of ordinary department stores. One end screws into the Schrader valve adapter of bicycle pumps. (Schrader is the big one, Presta is the skinny one for special tires.)
ShapeLock or other low-melting thermoplastic - these plastics melt at less than the boiling point of water, but become quite hard at room temperature
*Oil - pretty much any kind will do; cooking oil, Vaseline, machine oil, baby oil, whatever

*Vessel for boiling water in
*Microwaveable bowl
*Fork, tongs, chopsticks, or other tool for handling hot substances
*Small knife, compasses, or other pointy thing
*Air mattress (the one you want to inflate, obviously, but I think the valves are standard sizes)
