Give someone the bottle and say "bet you can't flip it" and then they try but half way through the bottle just leaves

7:07 looks like a really odd coke advert. "50% more upward thrust, Same great coke taste."

So I did this exact experiment a couple years ago for my college physics class. Got a 95% grade on it too. But anyhow I experimented with flat coke, carbonated coke and plain tap water. Each was experimented with at both room temperature and heated to 140 degrees. 3 runs of each of those combinations. Lots of butane and bottles used lol. The goal was to find out if the reaction was caused by additives in the coke, the carbonation or purely temperature. I timed each run from the moment the bottle launched to when it landed back on the ground to gauge how much thrust there was and averaged all the times for each liquid/temperature category. I also put the butane into a separate container and then poured it into the coke bottle to minimize the time it had to change the temp of the liquid for better accuracy of the experiment. What I found was that the carbonation had virtually no effect on the explosiveness of the reaction but rather the temperature of the liquid was most responsible. Basically the greater the temperature difference between the liquid and the butane, the faster the butane boils and converts to gas.

imagine a person that never watched a single video in this channel before and watch this video believing these 2 guys named Gav and *Sweaty*

"We're in a quarry today." alright, I like where this is going... tell me more.

Honestly, one of my favourite parts of these is 'Smart Dan' - the grenade lesson from way back was excellent.

That first one absolutely scandalised me. The expectation in my head was it would slowly take off like when people slam coke bottles down cap first. I didn't expect it to just delete itself in a frame.

Something about Dan calling the 2L big bottle an “absolute zwihander” made me crack up

Gav:Hello im Gav! Dan: *im sweaty*

People at nasa: Let's start producing coke

It is literally impossible to keep from smiling when Gavin lets out one of his squeaking laughs.

4:01 i love this instant answer gav: "where'd it go?" *bottle hits the ground and makes a sound* sweaty: "there"

8:27 “The Highpoints of Charlie Sheen’s Career”.

**shoots something into the air** **loses eye contact with it** **takes off protective mask** "Where'd it go?"

3:29 T-shirt: "I look even better in slow motion" Yep, you're looking great

its videos like this that remind you that Dan is actually incredibly smart and knows what he's doing at nearly all times, despite seeming like a buffoon sometimes :p

The explanation is clearly dan flexing his army explosives knowledge.

Coke and Butane? Sounds like a fun night in Vegas.

The harmony on the laugh at 3:28 👌🥵🦻

Dan being completely baffled by everything is one of the best parts of this channel

Slow Mo Guys: 1% Slow Mo, 99% Dan's reactions

Who’s this sweaty guy? You should have him on the show more often he’s super smart!

The expression on Dan's face at 3:30... that alone was worth the thumbs-up!

This video is such a great combination of science, cool footage, Dan getting messy, and hilarious lines like "I'm sweaty"

"Not to be done indoors, or a greenhouse" Had me chucklin' - sml

Gav: “God it’s bloody hot under this bag, it’s like a face sauna.” Dan: “Oh, do you want some coke?”

Question on test paper would be like: How many liters of coke and can of butane would you need to go to the moon?

My skin crawls thinking about how sticky he must have been afterwards.

Team Rocket blasting off againnnn “ding”

1:56 Sneaky flip of the bird to the viewers.

That Pokémon Team Rocket reference near the end really got me!

What would be awesome is a remote controlled bottle flipper with an ignition source! Now that would be great!

Please do a slow mo vid of laser tattoo removal, seeing the impact on the skin - that would be crazy to see!

now the movie "The Gods Must Be Crazy" makes sense :D

1:55 I love how he flips off the coke bottle

A note, as someone studying aircraft engines: A venturi reduces pressure. The principle is that the venturi increases velocity and reduces pressure, creating a partial vacuum. Once the gas leaves the constricted area of the venturi, it returns to ambient pressure.

The 2 liter upgrade was an epic idea!

Just can't stop laughing. This is the best

the shot of dan getting showered by the big bottle's takeoff is borderline religious and definitely artwork

When the coke evaporates, you are left with a candied Dan... Whilst the butane is contained in a dandy can... 🙂

4:00 "Where'd it go?!?!" **Thud** "Oh, right there."

4:57 the new “Nope!” Sound for the Internet! Thx guys.

There’s a frame at 4:04 where the guy looks like his right arm has been blown off and he’s looking down at the blood splatter on the floor

6:12 looks like Dan's worshipping a leaving UFO

"We're the Slow Mo Guys, we have been, for many years now." Um, you okay there Gav? You wanna talk about it? We're here for you bro.

5:49 - auto-generated English captions: "flippin' egg" LOL

2:42. Lighter fluid is flammable. The more you know

you need to make a collab with coyote peterson and get a bee sting in slow mo

"we learn about that as we go" *Happy* *Ryan* *noises*

imagine them being high school physic teachers doing experiments like this in a classroom and blowing the school up accidentally

The comedic timing on that second launch was just (chef's kiss). "Where did it go?" (thump)

2:46 In today’s episode of “Dan’s Assassination Attempts” Dan’s accuracy suffers when he fails to take propulsion into account.

8K Resolution at 50 FPS = perfect for warming up my PC for this cold winter weather

Dan explaining the reaction here is his best, he regularly seems like a buffoon but dude is well above avg intelligence dropping Venturi Shape casually.

I feel like Dan would be a really good teacher.

Now why wouldn't you leave cap on and try different sized holes in cap as a nozzle?

They're at this point just British Mythbusters

"Where did it go?" takes of protective helmet

Perfect comedic timing in 4:00 "where did it go?" -twamp-

3:33 the caterpillar from bugslife?!

Dan: *explains science of butane and coke* Me: YEAH SCIENCE!!

That was actually sick ! Love experiments like this lol satisfying to watch fasure

Great fun; thanks guys!

You know that the lab coats are old when even Gav's is dirty

I LOVE that face dan made! that just made my day.

Dan's slo-mo expression during the first launch was comedy gold!

"Where'd it go?" *PLONK* Rather good demonstration on comedic timing.

I love how Dan is still wearing the same lab coat! If they keep doing this till they're elderly, I hope he still wears it

Legend has it the 1 liter bottle of Coke reached the ISS and is refreshing the crew to this day.

"Jeez its hot in that bag!" pours chemicals into drink "want some coke?"

This episode solely made to remind everyone that dan is very smart

RIP old channel design, you will be missed as a classic. Hello new design, I welcome you with open arms

Dan's facial expressions are the funniest parts of these videos

'Team Rocket's blasting off again~!!"

Back in the day we would have attempted it with a flame near the launch or with the cap on but that would almost certainly be demonitised these days. 😬

3:33 this is possibly the MOST hilarious face Dan has ever made

0:01 “hello! I’m Sweaty!”

Incredibly funny, thank you for the video! Chuckling all the time! And, I didn't know the bottle had to be almost empty before taking off. Compliments - from the UK!

sweaty is the best slo mo guy: •can become liquid and spread over dan and gav to make them look wet •mixes well with coke

This is probably my favorite episode ever. I’m currently a chemical engineering student and it was fascinating to be able to understand all of the mechanics and properties that allow this to happen!

Team rocket reference 😂😂 loved it

Your guys videos make me crack up the entire time lmao You guys really know how to make me laugh LMAO

I get you have to say not to try this, but my first thought was, "I'm doing this tomorrow".

Reporting to NASA: Year 3019: Lets make rockets using coke and butane

you should do this again with a robotic arm (not the expensive one, just something to rotate it) and have a flame underneath, then when it blasts off it produces a huge fireball

Right before you showed holding onto the bottle, I thought about that exact scenario. Well done lads. Thanks for saving me a viddy.

Venturi doesn't increase pressure, tho. It increases velocity

Gav: Hello I'm Gav. Dan: I'm Sweaty. *B I G B R A I N*

I seriously wish you two were a thing while I was in school. My junior year science teacher would've loved you.

I spent to much time rewinding and watching the launches in normal time. The way they vanish is like a special effect.

As fun as the experiments are, the reason I keep coming back is because of the glory of the Slo-Mo Dan Faces.

3:55 Dan: I got covered! Where'd it go? Bottle lands behind him with perfect timing a second later Bottle has amazing entry timing.

2:29 It's alright, Gavin. Not the first time I've been bagged over the head right before something exciting happens.

Guys, that was awesome. 1st time on your channel. Never seen this before. ❤👍🍻

I'd like to see this done with a remote rig and an open flame. :D

1:18 "the liquid will escape rather than gas" Gavin: bwuekarghawelkk

Wow. Awesome. 🙂

I've laughed so much today watching your videos that I'm exhausted. Thank you, thank you.

Gav: hey don't leave it, catch it tight Dan: says "ok" from the moon

Put it out in a kitchen with a “pour out” note...
