Wham-O released a toy for children back in the 1960s that used this principle. It was around 6" in diameter and had a handle and trigger to fire it. Seems ever few generations every old is new again.
@uploadJ yes I bought some when I was a teen. Small bottle sealed with wax. Had to discard after opening. Walmart and bass pro shops sell all kinds of urine, used in hunting.
This is amazing and funny at the same time. When I was a kid or maybe a teenager you could buy a toy that did this exact same thing but on a much smaller scale. I think it was during the 1990s.
Add a wind tunnel inside the cannon to speed up the air within, then fire it off. I’m thinking it would give the vortex more velocity which could give it more distance. May have more damaging force, start small.
There is an optimal volume and speed. Faster just makes it unstable never forming a rolling ring. Just like blowing harder doesn't make a whistle louder.
The limit of energy is the potential energy of those rubber bands. You can not increase energy of the shot by narrowing the exit hole. More power could be gained if they used stronger rubber bands and more solid container to prevent losses (like 4 mm steel instead of that plastic).
Faster wouldn't create the vortex ring, just chaotic fast moving air. The vortex is cool because it stays organized and can carry an effect much farther down range than anything else.
@4:58 The plastic deforms, wasting energy. If it were completely rigid all the energy would go into the blast. The US Military made one with Gunpowder back in 1998 that could do 109 mph (48.7 meters per second).
Not biggest, child size actually. Nuclear Institute №12 in Russia has air cannon to simulate shockwave from nuclear blast. Its used for testing armored vehicles. They just putting the whole tank into the barrel of cannon and shooting it. Simple cars from 40-50 meters that cannon tears to pieces.
I would put in some type of plaster mold to go into a vortex a hurricane type swirl for air pocket vortex hurricane swirl with enough Force of 10 lb maybe 30
@@tanjmazmaz3731 the hail cannon does create a small shockwave but its focused into the vortex from the design of the cone turret. a explosion from the combustion chamber forces air out of the cannon at a insane speed then quickly stops. the cone shape of the cannon only stops the flow near the sides letting the air through the center spinning the air into a doughnut creating a vortex. the process is so quick it creates a shockwave inside the vortex in the process. here's the difference between a vortex and a shockwave. a vortex can be completly invisible if its just air with no smoke. shockwaves are always visible. shockwaves bend light and creates a distortion as it spreads out. in order to see a shockwave from a hail cannon you'll need a expensive slow motion camera to see it.
