Just a heads up, On the Science Channel, they're gonna have a whole show in regards to the latest Pumpkin Chunkin contest. Here's the link for their site - http://science.discovery.com/tv/punkin- ... about.html

For those who don't wanna check the link for times, PUNKIN CHUNKIN premieres Thursday, November 27 at 9 p.m. e/t on Science Channel and Science Channel HD.

wonder if anyone here is gonna take part in it?

Kinda doubt it. Most here don't have that kind of budget. Where I work now, I could conceivably construct a decent-sized pumpkin gun without breaking the bank, but there's still the task of driving it to Delaware from Ohio.

Also, I have a feeling the gun I'd make would produce nothing but pumpkin-flavored mist.

Yeah these guys take this very seriously and have way too much extra money and time on their hands. They also limit the cannons to air powered only...no combustions or hybrid combustions...dang-it...

D_Hall's new toy may be able to compete. However, I've got to think that a burst disk valve of any sort is going to be just too much energy too fast for the pumpkin to survive the launch...as you say Fnord, pumpkin mist. Same thing happens to potatos on even a 1x combustion burst disk launch.

that's the thing, most of those guys use huge tanks, really long barrels and ball valves so they can accellerate the pumpkin more gradually than the explosion-like bursts we typically go for.

Condense the mist and you've got soup!

But indeed an interesting show to watch. We might learn a thing or two.
Thanks for posting borg.

I saw a few of the giant air cannons, and as far as I know (which ain't much), I have no clue what valves they use. In the absence of a visible valve, I would assume they are using burst discs of some UNGODLY strength (aluminum sheets?), or have gigantic piston valves.

Honestly, these things are WICKED.

They use mechanically opened butterfly valves I believe.

They also use trebuchets, catapults and stuff haha!
About that pumpkin mist thing, They actually grow genetically modified pumpkins which are more aerodynamical and alot harder than normal pumpkins...

I'm pretty sure aerodynamical isn't a word
