jonstark 8 #7 September 27, 2010 Those handles have solved the line attachment problem. Wonder how fast they'll open?!?! You doing a roll-over or a tard? Using kite string? Can't wait to see the video! jon Quote Share this post Link to post Share on other sites
rdufokker 6 #8 September 27, 2010 Using FF thread, 4 into 1 line down to cutaway risers. Using a large canopy free bag tied to balloon. As far as littering, I have several vehicles to follow the bags when I cut away to retrieve them.Irony: "the History and Trivia section hijacked by the D.B.

happythoughts 0 #10 September 27, 2010 A similar instance has to do with hair. I saw a woman at the circus swinging while suspended by her hair. Opinions vary, but a single human hair will hold 50-100g. So, total weight of person / 60 would give the number of hairs that would suspend them. With plastics bags, the failure rate due to tears would be a factor. The weight would not be evenly distributed, but instead, it would focus on the attachment points. Also, the weight of the lines would be important. A 150 lb person being supported by 300 bags would only need 1/2 lb per bag (before considering line weight and percent of bag failures). So figure that each bag should support 1 lb. Really interesting. discount gear Quote The hijacker demanded the passengers to place their valuables in a bag before he commanded the pilot to descend and depressurize the aircraft so that he could escape by a homemade parachute made of nylon with a curtain sash for a ripcord. Before he was about to jump, he panicked and clung to the rear door, and a male flight attendant pushed him out of the plane. The hijacker was wearing a ski mask and swimming goggles when he jumped... Quote Share this post Link to post Share on other sites
chutem 0 #11 September 27, 2010 I make single grocery bag parachutes for my kid to play with. One standard plastic grocery bag works pretty well for a single little plastic soldier (you remember the little green plastic "army men" about 2.5" tall from when you were a kid). The little plastic guys weigh almost nothing. I'm thinking the decent rate will be fast even at 1/2lb per bag suspended weight. James Quote Share this post Link to post Share on other sites

heavydude 0 #13 September 27, 2010 Cool ! I cant wait to see this. Really if I wanted to be slick I could model this in Solidworks and do a mechanical simulation; al you have to do is model 1 bag and repeat. Sounds like a fun engineering problem. Are you using kevlar fishing string ? assuming multiple branches.High performance kite string is also strong, thats fairly cheap. Quote Share this post Link to post Share on other sites
rdufokker 6 #14 September 27, 2010 So I need 300 African Swallows? @Heavydud...I'm using double F thread, it has a 22lb break strength. Tied 5' line to each handle. Two bags(4 lines) tied to one 12' line. This equals 75 lines to each riser side. I just hope the weather cooperates for Friday afternoon. BSIrony: "the History and Trivia section hijacked by the D.B.

yoink 321 #22 September 28, 2010 Wouldn't some of the heavy duty garbage bags be a better option? Particularly as they'd have reinforcement in the drawstrings that would help your attachment points. Quote Share this post Link to post Share on other sites
