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

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

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.

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

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.

People at nasa: Let's start producing coke

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

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

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

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

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

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"

The 2 liter upgrade was an epic idea!

The explanation is clearly dan flexing his army explosives knowledge.

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

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

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

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

The harmony on the laugh at 3:28 👌🥵🦻

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

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

Just can't stop laughing. This is the best

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

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

Team Rocket blasting off againnnn “ding”

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

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

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

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

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

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

"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.

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.

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

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

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

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

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

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

They're at this point just British Mythbusters

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

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.

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

3:33 the caterpillar from bugslife?!

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

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

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

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

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

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

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

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

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

I feel like Dan would be a really good teacher.

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

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

Great fun; thanks guys!

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

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. 😬

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

That "Sweaty" dude is pretty good, you should keep him around.

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

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

"Where did it go?" takes of protective helmet

Team rocket reference 😂😂 loved it

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

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

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

That’s Your Best One so Far. Love It. Awesome.

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

5:25 did he say “absolute zwie-hander?” Ima have to use that one some time

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!

This episode is so cooool!!!

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

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

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

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

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!

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

A Slow Mo video I didn't watch yet? Exciting

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

The new logo is fresh, just like their content as always

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

LOOKS LIKE TEAM SLOW-MO'S BLASTING OFF AGAIN!!!

Wow. Awesome. 🙂

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

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

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

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

"hello im Gav. Im sweaty" fastest like ever

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

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

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

5:40 is Jeremy there? That sounded like his laugh in the background

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