Ballistic Gel vs 60,000 PSI Waterjet 

6:53 had me in tears the way they both looked up, two grown men grinning ear to ear at a fart noise made with shop tools. Never stop doing what you do!

First guy: *Mentions meaty thighs Second guy: *Instinctively slaps the gel block

7:42 - 9:30 Interestingly enough, I've learned more about the toughness of ballistic gel from this footage than people actually shooting it with various things.

7:45 humans before surgical tools were invented:

When I worked on waterjets years ago we tested how far from the nozzle the jet would remain dangerous. It's uncomfortably far. Much much farther than you would ever think.

Slapping that block is the equivalent of clicking a pair of bbq-tongs just to make sure it works. Love you guys, keep it up!

6:46 me on the toilet at 2 am trying to be quiet after eating taco bell?

dude that slomo looks so cool

Normal people: oh that's cool My brain: could use a a pressure washer for murder and it would be completely unexpected

The “myth” is actually true, that you can inject air into your body with an air compressor. It’s called a pressure injection injury, and the air doesn’t go to your heart or brain, just under your skin. With air, it’s dangerous and you may need surgery. With hydraulic fluid or something else, you need to have your skin opened up through the entire wound site, which can be a big portion of your hand, and have it cleaned out. Major surgery, sometimes leading to loss of a finger or hand. Be very careful around high pressure, even shop air.

3:30 The refractive view of the first cut so that allows top-down (plan) and profile views is way cool.

The 3 of you together works very well. :-)

The air compressor thing seems to be a mish-mash of a few things. Air compressors *can* cause a bubble of air between the layers of your skin when handled incorrectly, this is very painful and will leave you skin loose and awful afterwards, but its not deadly. Getting air bubbles in your veins is deadly, im pretty sure it can rupture them. The two aren't related but I can see why the mistake might be made.

Easily top 5 coolest results on this channel. The slow-mo shots with the cavities forming and vibrating for a bit are astounding! Though the air compressor part was a major facepalm moment. A completely solid block is far from a human body. We have blood vessels, many different layers and parts with varying physical properties. A cool test would be to make multiple connected veins in the block with a thin metal wire, and then try the air compressor. To simulate a heart you could fill a water balloon with something similar to blood (that's less viscous than water) that's being held in place in the middle of the block with a string or something similar while it hardens. I'd love to see that!!

That clip is from Indiana Jones: The Temple of Doom

6:25 what you have there is a safety nozzle, it is specifically designed to prevent what you describe

The air compressor just sounds like a long wet fart

8:30 The Waterjet Channel goes sexual.

"Like this is somebody who's got some meaty thighs?" "yeah" *slaps*

Just found your channel and love this type of content. Never change and keep doing what you guys want.

6:50 fart noises 😂 it’s so wholesome that they were laughing too

“Hold on I’ll be to your heart in a second” got me 😂😂

Damn... those cavitations were more intense than I was expecting

Saw this video and was super excited to see Dan and Mitchell both in a video again, then I realized it was released a year ago... sure do miss these old videos, glad I stumbled across this one that I somehow missed.

5:40 the air wont go deep inside your body, it will go through the outer hide and build a bubble between the layers of your hide causing them to rip apart internally at a big area... Pretty painful and probably deadly

6:45 come with me.. and you’ll be.. in a world of OSHA violations 🤣

Bro I just spent 14 min watching grown men play with high power hydrolics and ballistics gel like little kids and it was amazing.

Imagine having this setup on a backpack, some madman jus running around piercing hearts and brains with jet water, absolutely terrifying

6:50, *Those are some legendary fart sounds ever recorded in the history..*

RU-vid’s new record. Recommended 4 weeks later I’m proud.

2:10 What you're here for

You guys have great on screen chemistry

7:50 this gave me so much anxiety lmao, I dislocated my finger when I was a kid because I did that with a similar gel -with much less force

this video is probably the best at teaching people how hard actually are those blocks considering all of us normal people will probably never experience it first hand

4:34 he's thinking about taking this block in bathroom for fun

Pretty sure that air theory is true, I think it's called an air embolism, I'd really be careful doing that on your bare skin.

Homie can't even remember my boy Indy.....

You should try to go halfway through it and then put the air compressor and see if you blow it up

4:12 “look at that jeggale” lol the way he said it

Indiana Jones and the Temple of Doom!

its Indiana Jones and the Temple of Doom you dorks.

I like how this started out super sophisticated and scientific, but then just progressively got more ridiculous and barbaric.

7:06 - Dumb & Dumber, during Lloyd’s sleeping/ dreaming while driving (one of the best parts of the movie 🤣)

Mary Shelley's Frankenstein. Ripping the heart out! That scene always stuck out to me as a kid.

4:35 Oh my..

It was like the pressure increased in the cavitation bubbles, helping the jet push through

This beautifully shows the Bernoulli's principle . The faster a liquid is moving the lower its pressure. It's why when it stops half way through because the water slows down the speed gets converted back into pressure and starts inflating the gel until it rips and travels further. What was cool was how at the end the cavitation inside the cavity starts to oscillate causing it rip through the last bit even faster. 8:32 If you are ever at that guys wedding and they have one of those photo montages that you add that clip to the end of it.

I'd hate to think what happened to that ballistic gel after the cameras were switched off!!

*Mitchell's muscular gut vs 60,000 psi water jet FTFY

The water at the middle “I... I want to break freeeeeeee”

2:14 Now the block has become like the human: a topological donut

That "blob" you saw was exactly that. It was material that compressed upon itself.

That shot was so friggin cool, it looked like a weird bullet trail from the matrix....dammit, now i wanna watch The matrix.

*thumbnail* me: ow my arm hurts

oh yeah i want to see more of the last part XD funny af

Something about watching a bunch of grown men wrestle a silicone block while pumping air through a channel made with a water jet all to make a fart sound just makes me so happy.

Neighbour kids: will you play a water gun war with us? Me: of course lemme get my gun My gun:

7:07 Your talking about the first dumb and dumber when Lloyd was daydreaming and fighting that one Asian guy and was getting his butt kicked then pulled his heart out of his chest and put it in a bag then gave it to the man.

i think the reason it bubbles up like it does, is because the water is building up and slowing down, which absorbs the energy of the waterjet behind it until enough room has expanded around it to push the excess water out of the way and continue cutting.

The way you have to describe ballistics gel is the real consistency of a blended up human that's been poured into a mold and it solidified.

The heart removal was in "Frozen" right?

Feels Lonely here

I like how it went from shooting a gel block with a water jet to just playing around with it haha

The myth about the compressed air injecting into your bloodstream is true, don't let this video fool you. Rubber tips are relatively safe, however if your nozzle has a metal tip it is FAR more dangerous and would more than likely kill you with semi-light pressure.

That gel block is cleaner then most ballistic channels xD

That's terrifying, i mean imagine a murderer chopping up their victims with a water jet

8:33 GOATSE

Just a jet of water, that cuts through a human easier than a light saber.

2:07 why does he look like bootleg TomSka?

6:09 if you turn on subtitles it says this is music

I think your thinking of Indiana Jones and the temple of doom for the heart pull, or from dumb and dumber during Lloyd's dream during the dinner date. Lol

wish i could shoot my waterjet through mitchell's gut :(

4:52 this i how katakuri's burning mochi works. High pressure mochi flows inside , then it blows up due to sheer overpressure , although the effect is much more powerful with katakuri's strength

“Do you have a serial killer mentality?” “Probably not” “I would hope not, do we need to fire him?” “Probably “ 😂😂😂 don’t know how I found this channel but I’m definitely subscribing 💕😂

i suspect the slow down of the cutting is do to the water build up in the cavitation, the water is hitting water instead of the material until eventually it's pushed out of the way stretching the block and cutting resumes.

It was Dumb and Dumber, Loyd rips a chef’s heart out and puts it in a paper bag and gives it back to him

Didn't expect to see this video end with them attempting to goatsie the ballistics gel

The movie is Dumb and Dumber when Jim Carrey rips out the guys heart and puts it into a to go bag. As soon as you said the movie clip I vaguely remembered until I thought of a comedian doing it.

When the ballistics gell got shot with compressed air and said "irrrrrrrffllpllpllppllllppllthththpllerrrr" i felt that....

A few years ago me and my classmate were messing around with an air compressor in shop class, and we'd put it between out arms and it made funny noises. I miss high school ngl

New name for this video " Bunch of adult men doing random stuff with a block of gel "

Cavitation is a hell of an effect

8:15 This would make for a great mortal kombat fatality. Character tries to get to someones heart, says my fingers hurt, and then just shoots the person with a water jet.

5:42 that true also even if it doesn't cause a bubble to enter the bloodstream, a pressure injunction injury is not good either

2:45 I think its due to this: with a waterjet stream, you have a low density object, and its going at about the same speed (depending on the round, and the gun firing it) a bullet. This making it so since more mass is going to be used, and the density is lower, and it is spread out over more time, there will be pockets made by water that has slowed down due to resistance In the gel. A bullet does not have those pockets, because all the mass is in one area, so slowing down it just stays in place.

The bubbles are probably not heat,but more of a backlash build up. Pools of water accumulated in 1 spot and kept creating a whirlpool of trapped water and air.

I work with a lot of high pressure water, a water injection injury should be treated with the same severity as a gun shot wound. Can even be worse depending on the cleanliness of the water used.

"It's harder than a steak would be" Not when the steak was still walking around it wasn't 😂

5:10 the block saying "hahahahahahaha" 😂 😂 😂

You guys should do Tungsten vs Waterjet

HEY, hope yall read this, it isnt that a bubble will go to your heart. What can happen is the moisture or small particles can enter the skin and cause an infection, which can sometimes lead to gangrene or sepsis. I had a coworker that it happened to.. And i knew people also from the past, ive been an auto tech for 20 years

Girlfriend: He's probably out cheating on me. Me and the bois: 6:48

water pressure release is what makes the final inches faster, no water comes from behind

fun fact. Ballistics gel isn't actually meant to replicate flesh. it is made to provide a uniform medium to study the trajectory of bullets and other projectiles. that being said, at those speeds and forces, it doesnt really matter.

2:40 my guess would be that it stopped due to the water that already made it into the block, stopping the stream before it could hit the block itself. As soon as that got sorted out it dug deeper.

Hey I did some googling and it sounds like AIR COMPRESSORS ARE DANGEROUS!! OSHA says not to point an air compressor at your skin if it's over 30 psi, and the bubble in the blood stream thing is called an air embolism

these guys look like good bros its wholesome

Not hard spots in the ballistic gel. The water slowed down halfway through due to the gel and built up pressure. The gel started to stretch to allow more water to build up before finally building up enough pressure to burst through the rest of the thickness of the gel.

You can actually get an embolism from the air comoresser. Had a guy spray himself off with compressed air at work and he suffered a heart attack from air being transmitted from the air nozzle to his veins. It's not super common but it's possible.

Who needs guns when you have a hydraulic laser
