Indeed 😂

higher education means you get the degree and you can knock those “big” company’s door. It just means you can choose a job position you like without been blocked by that “degree barrier “

Or like 100,000 frames a second..

@@devan2462 that's what he said

It gets mutch slower.

@@ERR0RR What about an aluminum ball bearing?

@@0neDoomedSpaceMarine It gets not so much slower lol.. But still slower.

@@Sidowse Well, probably not, it would be too soft for that. I was more just thinking a lightweight metal projectile, an aluminum ball.

@@0neDoomedSpaceMarine my air rifle has a higher muzzle velocity than my .22 - but even though the projectile comes out faster, the lighter air rifle has nowhere near the range, or impact. Wind resistance washes off its speed MUCH quicker. The projectile would also need to be a reasonably good fit in the barrel or the air will blow right past it - inertia. More weight means its harder to get it off the starting line...

I was wondering the same thing.

yes it would if the pressure is high enough. but not on a ping pong ball. the blast will smash it before it exit the barrel. a airsoft bb could do the same damage but with a different setup ant a lot more pressure.

The ping pong gets obliterated. It was indeed the air traveling at 'super sonic' speed that created the hole.

T Grey Actually the air travel lot faster than supersonic. My experiments showed me i can dig into concret with the power of presurized air. Use "GGDT" software to simulate a gun.

In the longer video, he explains how the tape is popped, by the air, which encases the ball, as soon as the air is released. This encasement also prevents the ball from losing speed, by hitting the tube or barrel wall. In short, obviously the pressurized air, is responsible for much of the impact. What I'm wondering, is why the ball doesn't pop, once they draw the vacuum? It's made of brittle material. This leads me to think, that the ball must have a hole in it, and is filled with pressurized air, as the air encases the ball. So, it has a wall of air around and behind it, and may be filled with pressurized air, as well. Who knows lol.

That's a good question 🤔

I know this is a few years too late. but the ultimate limitation on punkins is how fast you can accelerate them without making pie. That is why you see longer and longer barrels and centripetal machines that can almost match the cannons.

So do not attribute to Allah equals while you know [that there is nothing similar to Him].

( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠️ Quran

800 mph.

Or he got the idea from Mythbusters!

Lack of a true seal...mythbusters had a similar problem with their version of this and they found it was their vacuum's seal

Most likely the membrane material doesn't rupture easily enough. Best to have something barely strong enough to hold the vacuum. 12um polyester film (space blanket) works well.

Gamezob I hope you didn't want to say that science is an evil :D

Steve-o would say yes

what? No?

Hardly, this isn't patented, and they even said they found out the solution on the internet.

playing ping pong

Uh oh, someone making sense, better cover yourself.

The towers weren't concrete.
