Planning a trip into the great outdoors? Remember B.Y.O.D.T. In less than an hour, with less than one roll of Duct Tape, you can have your own hammock to sleep in instead of on the rocky ground. Even better, though, you can take it with you the next day because it only weighs 1lb. Materials: 1x Roll of Duct Tape (60yds). $3.34 at Home Depot Some string may be handy to help hang the Hammock while you are building it.
