To everyone asking what it feels like, imagine belly flopping into a pool, but the water turns to air right when you hit it, or someone slams a door in your face but it turns to wind as it hits you. It slaps your clothes against your body with enough force it kind of stings. Overall it’s not that bad, it’s actually fun! I explained all this in the video… but the first shot knocked my mic off and I was stepping on it when I talked about it haha.

Sir, this is not your backyard.

Yo! That video editing trick amplifying motion was pretty cool!!! The vortex gun was cool too I guess !!!😁

“I’ve worked up to courage to be hit by it” My intrusive thoughts have been validated and I can die happy

“So why are you at the ER today?” “I had my chest caved in by a vortex cannon” “I beg your pardon!?”

adding "vortex cannon" to my christmas list this year

I want to see this on a foggy morning

4:35 when the guy who created the sound uses more effort than the writer

Seeing a shockwave like this is so awesome. You’ve turned a concept into something visibly real.

This man is creating new lists to be on.

7:12 you sir have extremely specific childhood dreams

7:03 man to be hit by vortex, man to be happy

Try shooting it in high humidity and see if there's a condensation ring like when a tornado gets strong enough to appear like a funnel.

Kevin is building quite the arsenal; A car mounted megawatt laser cannon, the focused laser cleaner, a liquid metal squirtgun, and now a freaking air cannon. I probably missed a few implements of destruction but you get the idea

I didn't really expect that you actually let this thing hit you! This footage was amazing!! You can almost feel the impact! 😂🧨

5:51 seeing the cannon slowly get closer to the porta potty was hilarious

That 'tearing' sound sounds a LOT like artillery. Or at least what artillery sounds like in every movie and game I've seen.

The sound that thing makes is absolutely wild!

I love how the sound of the vortex just gently stopped when it hit the tree love it! 😂

That air visualization editing trick was phenomenal.

Good sir you can’t buy all of Nevada as your backyard!

That editing trick to show motion was insanely cool. Wow.

I've hit my 2 year cycle to check if the backyard scientist is still alive.

Those vortex hits look like way too much fun to be legal! I love it! I would totally pay for this at a carnival to be hit by such a vortex cannon a couple of times haha.

VRAD is such an appropriate name, because that is indeed very rad.

That's an impressive vortex gun. But it's interesting that the air comes from the outside, yet it have almost no airflow related design around the outside. It would be cool if it had some sort of sloping taper to bring in more air. Maybe it could be even more powerful.

1:38 "Slightly bend the air like a lens" No, that's not what lenses do.

6:07 "prank em John"

5:50 - How it feels to be held hostage while doing a commercial for hack pack.

I love how you've used video editing for science haha This is great

The cannon was cool, but I was more impressed by that tree. Just a single lone tree in the middle of nowhere, and it survived being shot by a cannon!

i really should start my homework...

This would be an AMAZING practical "special effect" in all sorts of things, like when they have those minor shockwaves in DBZ or some of the more modern superhero movies. All of the fabrics suddenly whipping and the minor stance change from the actor would make it look super neat.

You always share fun videos with us and I appreciate every minute of it. I always look forward to watching your new videos

Built a vortex cannon from a 55gal drum, using an old Popular Science article with my nephews when they were 11-12yrs old. They stood in front of it & me not paying attention to my backstop, ended up blowing a couple windows out of the front of my garage. I always loved teaching them fun stuff like that. No matter what the resulting carnage!!🤣

6:30 Imagine if the portapotty was full.

That cutaway bit at 0:26 absolutely killed me

You getting hit by the vortex cannon is the best thing I've seen in a while. It looks like it absolutely thrashes you! XD Great video!

We did that with industrial air ducting made from cardboard 3 meters long 25 cm wide and balloons filled with “stuff”and would drop a firework down them to fast pressure. It would eject whistling rings for about 50 m in the air. They were so neat. Was my favorite thing at those Fourth of July beach days.

One of my all time favourite pieces of videography is the slow motion of explosion and the visible pressure waves they create and seeing the vortex cannon showing its messing around with air did not dissapoint either, the rest is pretty cool and impressive but seeing air manipulated to me is just stunning

I want to see this thing shot at: A pond/pool, a large patch of chalk dust, a roaring bonfire (can it actually feed it if the fire is big enough?) a filming drone, a paper airplane in flight, a kite, and, of course, a pile of flour near an ignition source.

just the sound itself is already amazing holy

"I dont like that at all!!" Clearly loves it 😂

How many doomsday weapons do you need to have before you legally become a "Mad" backyard scientist?

I don't think I've seen you any happier in a video 😂

I love how upbeat your video is about a cannon

Meanwhile a checkup in a hospital. Doctor: sir, your inside become a smoothie

I'm in love with this

Hi im TheBackyardScientist, welcome to Jackass 6:15

This cannon is FREAKING AWESOME :D one of the best thing ive ever seen !!!!

Im glad this guy never changed Hes still the cool scientist who makes fun vids I was a child when i found him im an adult now still love the vids

That sound is WILD!! Sometimes you hear something and you’re just like “someone needs to use that in a movie.” Alright. I’m back to say I just got to the part where it’s explained that it’s already been used as a movie sound effect so… good for them haha!

This video is going to go off. No pun intended. It’s full of “whoa!” moments.

He nailed me that time is a wild statement. You gotta say no diddy after such statements bro 😂

"ive never felt anything like that before"........proceeds to turn into one big bruise 😂

I was JUST watching videos of hail cannons and literally thought “What would happen if that vortex ring hit you?”, and then this was uploaded as I was thinking that.

Definitely a cool canon. Glad to have you back

oh wow! that's pretty strong!

"Fire! FIre! Fire" THEN gets out of the way... priceless.

Somehow this man survives yet another recording process.

Oh my lord 6:51 looked terrifying

The editing is what sold me. Vortex gun yada yada, but software can effing do that? Omfg?

Oooh I like the “Haas effect” you used on the video edit to see the vortex…works really well to make audio recordings get that “wall of sound” effect

So this is what it feels like when Saitama throws a punch at you from a distance...

Okay this has been one of the coolest videos I've seen in a long time.

what if you jump while getting hit?

Bro go one of the oddest childhood dreams of all time…. I tip my hat time to come up with the next

This video put a smile on my face! Happy Friday America!

I love that motion visualisation with the difference. Thanks fot showing that!

So cool! Actually seemed like a seriously good drone disposal option, in Marks video

"Practical use?" "Look what it did to the boxes!"

Now imagine that vortex cannon to be really advanced and powerful = weapon of the future, no ammo, just pure unstoppable obliteration!

that was the coolest thing i've seen in a good while

You should have won the drone challenge with this, but still glad the boys got together to make a 10min commercial 😅. Of course William finished his device at deadline.

the worlds most inconvenient but cool fire extinguisher

I have to admit this is incredible! You should do a crossover with a Slow Mo Guys

You should really post a couple clips of the vortex cannon firing with no commentary or music, that sound is magnificent

1:32 this is epic

V rad is a great name for this

How is this guy not one the wanted list yet?

Kevin, the most florida-man of all the florida-men! Loved this vid!

4:30 At least one thing was (V)RAD about this movie after all.

Bro really pulled mark robers kit out of the toilet! 4:46

The clip of ElectroBoom shocking you is gold

He finally posts a video

This looked like a fun time..! Great video.! Thanks for sharing your awesome creativity.!

Vortex Cannons could be used to simulate warzones as a museum exhibit or outdoor re-enactments.

Ayooo this man is crazy AF talkin bout "FIRE, FIRE, FIRE" while he and his crew still in the line of fire, bruh

Wouldn’t the pressure change mess up your ears?

The music at 6:24 is a instrumental version of Lupus Noctre, & Zorro - Cry when it's Over

I remember when a teacher had a toy version and allowed anyone to use it while we were doing our labs, and it was fun just using it.

Thank you very much for the video it was a nice tone

The air sweepers in clash of clans when you deploy the dragons

id like to see this connon in heavy rain

This was very cool to watch!👍

Bro has a biggest backyard in the world Also that gun sounds incredible

i have to admit, the "effect" of you being shot by an invisible forcefield... Its hilarious

Thank God you are back! You are my favorite youtuber

Our airport uses "propane sound cannons" and they operate on a similar principle, but instead of generating a vortex they generate sound. Very good at keeping birds and small animals out of harms way relatively harmlessly (as in they save far more wildlife lives than they put at risk). Neat so se that a cannon operating in a more "dangerous" capacity has little effect on the human body same as the sound cannons on wildlife.

Awesome canon! As an environmental engineer I have a few suggestions: grind down the welds flat in the barrel and polish off the rust to keep a lower Reynolds number.
