Step 1: Gather Materials
#Duck Tape (I say Duck because that's my brand of choice :P)
#Bottle of Water
#Can of Soda
Step 2: First Steps - the Nozzle
When you're ready, crush the can and make sure you get a sharp edge.
Close the bottle of water tight and press that sharp edge into the upper portion of the bottle (anywhere will work though). Once you have a hole, rip the bottle in half - use the can edge if needed (if you can).
Now, tape the opening of the bottle (your filler nozzle) to the opening on the air mattress.
Step 3: Make the Duct
Step 4: Attach to Fan
Step 5: Final Step
Walk around your temporary shelter... have some slim fast... apparently they thought college students would enjoy a whole pallet of strawberry slimfast... note to self: strawberry slim fast tastes like quick setting concrete when room temp.
