The series sometimes showcased fan duct tape creations. The series had a feature film based on it entitled "Duct Tape Forever" and several VHS/DVD compilations of the show's use of the tape have been released. Since 2000, series star Steve Smith (as "Red Green") has been the "Ambassador of Scotch Duct Tape" for 3M. The Discovery Channel series "MythBusters" featured duct tape in a number of myths that involve non-traditional uses. Confirmed myths include suspending a car for a period of time, building a functional cannon, a two-person sailboat, a two-person canoe (with duct tape paddles), a two-person raft, Roman sandals, a chess set, a leak proof water canister, rope, a hammock that can support the weight of an adult male, holding a car in place, a bridge that spanned the width of a dry dock, and a full-scale functional trebuchet with duct tape as the only binder. In the episode "Duct Tape Plane", the MythBusters repaired (and eventually replaced) the skin of a lightweight airplane with duct tape and flew it a few meters above a runway. Garrison Keillor's radio show "A Prairie Home Companion" includes comedic fictional commercials sponsored by the "American Duct Tape Council". The "duct tape alert" refers to the recommendations made by the U.S. Department of Homeland Security on February 10, 2003, that Americans should prepare for a biological, chemical, or radiological terrorist attack by assembling a "disaster supply kit", including duct tape and plastic (presumably to attempt to seal one's home against nuclear, chemical, and biological contaminants), among other items. The recommendations came on the heels of an increase in the Department's official threat level to "orange", or "high risk", citing "recent intelligence reports". According to press reports, the recommendations caused a surge in demand for duct tape. The media sensation surrounding duct tape was fodder for comedians and satirists. Some referred to it as "duct and cover", a reference to duck and cover.
