OMG drinking straw flow stabilisers on Mythbusters

[CWR]

Seems Bills drinking straws have made their way to the Mythnusters makeshift wind tunnel

[Jim]

yeah, worthy! Bill, you have a lawsuit opportunity haha

[canthinkofone]

I fell asleep. What were the results?

[Norbie]

Results: a fast train might knock you over, but it has nothing to do with vacuum and it won't "suck" you onto the track. Which is hardly a surprising result.

Yay, I rock!

(In Manila at the moment, on the way home)

and both concrete planes sucked at flying (though Jamie's probably would have worked if he had've run it on the guide wire like Adam did).

[Mr Ed]

I dispuite Adam's results. I could make a brick move at a 4:1 ratio of movement:fall if I pulled it fast enough with a string, and yes he did continue to pull the thing after the pin was released.

I also suspect Jamies plane might have gone a bit better if he didnt add so much weight like the NASA guy told him to. :p

link to clip anyone?

didnt catch it on tv

[PLAYA]

at my uni they have a 1m x 1m square that is full of drinking straws in their wind tunnel

[2JZR31]

Has anyone got a link to the original drinking straw thread? I missed it.

would like to have seen the same test done in a subway/tube/underground

^^^ Was the mesh the only source of filtration?? And how far away do these straws need to be from the air flow meter or does it not matter.

[stockymcstock]

those glider tests were utterly useless. the POS one stalled straight after release and the flying wing pitched straight down. neither of the wankers thought to put even a controllable elevator on them so that they would actually pitch properly. the minutest fuckup on the tail fins would have totally sent them to shit - and it did. wankers.

Jamie's looked like it wasn't trimmed properly and/or the centre of gravity was too far forward. It may have done OK with more up elevator. One of the first things you do with an RC glider is trim it for a stable glide from a few hand launches. I guess you only get one go with concrete on concrete.

They didn't really deduce a proper glide ratio for each because neither had time to stabilise in the glide - they should be looking for a straight line, not an arc. Admittedly that would have been harder for them to test but maybe they could have used radio control to deal with trim and a greater launch height would have helped.
