"Lawn Chair, Two O'Clock, One Mile..."

They couldn't duplicate it on their show, and considered it busted. But a good friend of mine was trying to move one in a church that was under construction. He accidentally drove it into an orchestra pit and was thrown across the sanctuary. That's very different than what they were investigating on the show. On the show, the conditions involved suddenly removing a lifted weight, causing the arm to suddenly apply the lifting force in the opposite direction, launching the occupant as a projectile. With all due respect to your friend, it sounds like he was thrown as one set of wheels fell into a hole. This is totally different, very easy to understand, and unfortunately, it happens on a regular basis. I work for a utility company, and guess what happens when a line truck with the boom up gets hit by a car? The same thing! This is why body harnesses are OSHA required when working aloft on a platform or in a bucket. We've had technicians travel a surprising distance to their death as the parked truck was rear-ended and the harness wasn't attached. |

Calculating the lift is really not that difficult. And even if you cant calculate it , how hard is it so simply measure the lift of a single balloon on a scale to determine how many balloons are requried to lift the desired payload. I remember doing this my 10 year old daughter using party balloons and a kitchen scale. I recall we calculated about 5000 party balloons were required to lift a small person. http://www.mythbustersfanclub.com/mb...nt/view/61/27/ Mythbusters miscalculated and didn't explain why their calculations were off. They thought 1700 would lift 40 pounds. It took ~3500 to get the effect they sought. One guess: they were conservative in filling the balloons on the day of the test and didn't put as much gas in each balloon (on average) as they did in the lab. Or there was some weight in the tethers they used that they didn't factor into their prediction.

He was able to successfully argue that his lawn chair did not need an airworthiness certificate. That charge was dropped and he setted for $1500.

Or a Leatherman, for today's suburbanite; doubles as a bottle opener. Not much chance of putting out an eye with an errant missile then. And no danglie strings to snag in, ummm, powerlines. |
