....And that brings us to numer two.. I submit the Trailer-Trash-Cannon. First acquire three galvanized trashcans anchor the first to the ground at an angle approved by N.A.S.A. The second can should have four vents in the bottom the size and shape of pizza slices,and be inserted firmly into can number one. The third can should have the bottom cut out completly and then be inserted into can number two.... pour in approx. 5 gals of high-test gasoline and then climb in and light a match During your flight feel free to visit the International Space Station for a inflight snack and don't miss the gift shop
