Ron JL White : Hit the rod with a hammer. No air will be introduced to the experiment.

Jase Poag : Wish we could have seen it without the outside air being introduced by the rebar.

vcval : Will you be doing it again with the rod already in the water so no air is introduced ?

cuckoo head : video starts at 2:10

jiberish001 : I was disappointed. I would really like to see this redone without the captured air from the rod. Simply place the rod into the water before putting force behind the rod to smash the glass. IMO the captured air ruined this experiment.

Flávio Kobori Noguti : can you do it again, but instead of punching it with the rod/rebar, you could have let the rod/rebar rest one the glass and hammer the rod/rebar to break the glass

Mr. Nicholas : You shouldn’t have jammed the rod into it like that. You should have set the rod on the glass jar and then hammered it lightly on the other side. It would have stopped all the bubbles from the rod showing up. The test would have been a lot more accurate this way.

Tim Michaels : Hey, same action takes place in my stomach after eating Taco Bell. 😶 _Yo Quiero Taco Bell_

Alex Maxwell : The balloon represents my mind when I learn something new in science

Secret Person : That moment when you try to be first, but you get an unskippable ad!

Justin Y. : Deja Vu, I've seen a similar video before...

PressTube : Damn! This is an awesome video my friend!!

Will Stamatakos : Hey look I have a comment someone might notice

JQuery : 1 like = 1 push up

Gonzalo Rios ley : Thanks for showing the world how fun science can be!! Hii from Spain

Indian Technical : Sir today is my birthday 🎂🎂

Galactic Kitten Universe / Kitten clans TCG : i ordered the subsciption box :)

J Bolo : And that's why I don't like submarines

Donald Mach : You put a balloon in the jar to confirm a vacuum was forming. What would have happened if it was a small water balloon?? 🤔

Sion : *@The Action Lab* Can you do this experiment again, but this time make a test-stab first, with the rod starting a bit into the water, this should prevent the air-bubble from forming around the rod, if it works as I think, then stab the vacuum chamber again with this "non-bubble technique". Good luck!

Ayush Chadha : "smash into nothing" Dude that voilates quantum mechanics

Glitch : I love your videos, Action Lab! :D

Freizeitflugsphäre : I don't like the thumbnail. Though the video is quite well done.

Pro Player 1⃣ : I doubt there is a bubble

SlimeMCPlays Mendoza : What would happen if you fly a drone in the vacuum

Purifier Phoenix The Mecca : now put pressure inside the jar until it bursts.

Private22 : Remember us when you get REALLY REALLY FAMOUS

Kristoffer Vassbø : What happens if you put a vacuum chamber inside a vacuum chamber?

DoubleJ : Do it again and rest the rod on the glass jar and hit the rod with a hammer. Let’s see it without air being introduced or brought in. It still looked cool though in slow motion.

August Nyblom : You are awesome.

William Lanier : First

Momma O : wow that was way cool! l loved it and l was surprised there was no sound too, Amazing! Gotta get me a subscription box, hey wait, l'm your mom, just give me one :)

Edward MacLennan : I propose that you do it again, with a rod in contact with the jar, and tap the rod. Also, try with a colored mixture in the air in the room, or an alternate lighting method so that "vacuum bubbles" which are actually voids, look different than air bubbles.

dale carter : Would you film that once more with the jar vacuumed, but with the metal bar already in the water so it does not bring air with it to the vacuum. If you are worried you can't break the jar, just tap the bar with a hammer on the other end like a nail and it should break the glass.

GeoDrone : Why didn't u place the rod on the glass first, then hit the rod with a hammer. This way there is no air brought down with the rod. You would get a truer event, which I suspect would just be movement of water with very few bubbles.

Brucey : *Love These Videos!!*

David k : If you had held the rebar against the glass and tapped it with hammer you wouldn’t have had air bubble suck into the vacuum in turn you would have had a more controlled experiment.

Keaton MacKenzie : This is gonna be a cool experiment

Super Red Boi : 26th

Toast Music : #StopVacuumChamberAbuse Lol jk 😂

Naruto Uzuchiha : Lol 3 firsts...ha ha

Fazlı Eren : what would happen if we drop a hot metal ball with air inside that normally flows on top of the water. will it flow or will it sink and then flow again ?

Albin Dahlkvist : what would happen if you carefully put down the rod so almost no air gets pulled down when you destroy the jar? Would be really happy if you could make a video on this!

josh daniels : Have the end of the rod submerged slightly before thrusting it down, the air seems to be brought in because of the rod having to break the surface tension of the water

Tequiza79 : You should try a spring-loaded punch to break the glass underwater so we can really see what's happening. The air from the rebar is convoluting your data!

JathTech : Should have put the rebar against the jar and then hit the bar with a hammer... no air bubble transfer that way.

Hardi Saputra : Please try wet paper or wet potato chips in vacuum

Joe Takacs : You've gotta redo this in a deeper chamber so the device used to break the glass does not introduce air into the experiment.

Atticus Trevino : Can you put black cat fireworks in vacuum and set them off with laser?

Richard Perryman-Smalley : Can you do the same with a fire or heat the jar with a blowtorch ?
