something constructive for once

[urgle the danish cow]

for those who remember about august i was asking for any ideas for confetti cannons for my nephews "show choir" well i made them when i was visiting him in december and have been waiting for a good video of them.
the video is from a competition (which they won 1st place)
btw the schools they compete against started rumors that the confetti cannons cost them $3000. that just makes me kick back and laugh.

now to business;
there are two confetti cannons with 3/4 sprinkler valves that are wired to a control bow with an "arming" switch for safety and a "fire" button.
the barrels are 2.5 feet of 1.5inch pvc
the air chambers ride below the air chambers with a pvc support on the end and are also 2.5 feet of 1.5 inch pvc
attached to the end of the barrel is a string 4 feet long made out of some mixture of steel and fishing line which is attached to a cloth wad that helps fling the confetti out.
the two cannons fill the 100X50ft stage with confetti and reach 25 in the air.

sorry this is the best video i could find pictures soon!! the camera doest show the confetti the best but in person it is amazing. SKIP TO NEAR THE END OF THE VIDEO FOR CONFETTI

Oh dear... it makes me wish you had loaded them with buckshot instead but seriously, nicely done, you achieved a good spread

when i tested them in there infant life i used 10 nerf balls in each barrel. that put a new definition to the term "nerf"
