[NightHawkInLight] has been establishing his style for a vacuum canon for a while now, so it seems fitting to decrease in inspect out the progress. The concept is quite straightforward, take a long stiff tube, insert a close fitting piston, magnetically connected to a projectile, as well as stopper the open end with something quickly destroyed. The piston needs to be pulled into the tube with some force, to pull a vacuum against the stopper. The fascinating bit occurs next, when the piston exits the other end of the tube, with the vacuum at its maximum, there is a unexpected inrush of air. obviously this inrush of supersonic velocity, as well as the momentum of the mass of air is adequate to eject the projectile at significant velocity, smashing with the plug as well as demolishing the target. So long as the target is of the soft as well as squishy range anyway.
It’s an fascinating idea, as well as definitely provides lots of bang for not many bucks. That huge lump of acrylic tubing (presumably utilized for simplicity of explanation in the video) looks relatively costly to buy off the shelf, however we reckon any type of old pipe would most likely work out fine.
We’ve definitely covered our share of diy projectile weapons, such as this air cannon made of PVC pipe parts, as well as of program there’s this crazy huge one, that you should definitely not try at home.
Thanks [Keith] for the tip!
