I once glued and taped something like 5 of those bottle together for one monster 10 liter water rocket. I decide to test the thing with my 10 year old little brother (it was maybe 15 years ago) on our backyard. I was pressurizing the thing up to 8 bars with bicycle pump and maybe 4 meters long hose when it exploded around 5.5 bars. We both thought that it was the greatest thing ever but my mom was super angry since it was stupidly loud :D

Wonder what the neighbours think when they hear laughter and explosions from your garage (Honey he's talking to the pvc pipes again)

That's some really awesome fluid dynamics and a great use of high speed footage! Great video

What Is Islam? Islam is not just another religion. It is the same message preached by Moses, Jesus and Abraham. Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus. Rather it’s going back to the original teachings of Jesus and obeying him

I really appreciate that you make predictions before you do the experiments and are willing to leave those in during edit even when you're wrong. Kudos for showing good scientific discipline.

The brighter and lighter the colour of the flame, (the blue flame front) the more stoichiometric the burn is

“More on that later”? I had to double check I wasn’t watching a Practical Engineering video.

These are some of the coolest slow motion shots I've seen too date and the shots demonstrate some really interesting things too. Thank you so much for sharing!

This video reminds me of the times I made potato cannons 'sing' by filling the chamber with a rich butane/air mixture, keeping the barrel empty, then hitting the ignition. The one that made the coolest sound was the straight-pipe cannon measuring about 4" dia x 72" long. Too much fuel in the mix = slow burn = loud, twangy, bassy howling.

Ahhh, loved those slow-motion shots!

I'll be honest I'm enjoying this more because you seem really into the project and really happy. Also that's cool. And dw just add more tape. Anything can be fixed with more tape.

Wow, it’s been a couple of years since I’ve consistently watched your content. Seeing this and your Starlite video makes me wonder why I stopped. Your videos have done wonders to keep alive the interest in STEM and the way things work alive in me. Thank you. Now I’m curious if something as simple as a rubber washer on the bottle launcher would keep the bottle where you want for the ignition point.

Place a pressure gauge in the wall of the bottle with a “tell tale” pin which will show the maximum pressure achieved during your various fuel to air ratios as well as with the differing points of ignition. Great video. Looks like loads of fun.

Famous last words, "I did not mean to hit the trigger..."

Awesome video. I love the slow motion, it really shows what's happening. Also, thanks for plugging my tutorial!

This video has a lot more of you speaking in real time rather than narrating in post. Your delivery sounds really natural this way.

Your adrenaline fuelled laugh got my miserable fizog to grin like a Xmas day child unwrapping prezzies. Thank you. Oh, the science stuff (witchcraft) was interesting too!

Glad to see you're posting again!

I've been making potato cannons for ages with that technique. Tape works brilliantly, but to get them to last a long time you want to make sure the direction of flow won't be going under the seam.

(videos on my channel of them btw)

The reason it burn faster when at the back of the botle is because the fire starts all the way back in the pvc pipe, the air fuel mixture is accelerated into the botle at speed before full ignition, causing turbulence. (Similar to how a diesel engine with a precombustion chamber works)

The slow motion cameras have sure changed the way we look at so many things ! Highly entertaining ! 😊 Thanks for sharing and take care. 👍

Love these videos, especially when seeing your genuine excitement to things you find cool!

I've learned more in this 20 minute video about science than I have in 4 years of high school and 2 years of college! Really loving the videos lately! Keep up the great work!

What I love most about this video is how you are so much more candid and genuine. It's like seeing the real you and excitement

First 19 minute KZread Video I haven't skipped forward on...So entertaining!

I've been watching you for years, and everytime I get a notification, I can't wait to get home and watch them! Great content!

A couple of months ago I watched this video knowing literally nothing about rockets. like, absolutely nothing. But, I thought this was the coolest thing and I was determined to create a rocket engine. Soon enough, that goal changed into creating a full on rocket, and to get it into space. I started researching straight away, and I found another one of your videos on the hybrid rocket engine. I immediately started working on it, and It actually worked! Something you should know about me is that I never, and I mean NEVER finish projects. I always start them, but move on to something else. So for me to build a working rocket engine, that’s a huge achievement. I started doing more research, and I started looking at liquid fueled rocket engines. I started learning about things like the turbines, oxidizers, fuel pumps, injectors, over/under expansion, and a lot more. I am now currently working on a liquid fueled rocket engine, and it’s going great! I owe it all to u. My goal right now is to start my own rocket company, like SpaceX. I know it sounds crazy, but I’m working at it. It’s weird to think that all of this never would’ve happened if you didn’t make this video, so I just want to thank you for making my dreams come true.

Absolutely love your videos. That slo-mo was awesome! The flame front and jet out the nozzle was super cool. Thanks!

explosions make me happy too, keep up the good work! :)

Super cool! Thanks for sharing.

I absolutely love how much you can learn with tests like this and a good high speed camera! Thank you!

I remember that smartereveryday dude did some ignition tests to analyze the shockwave but it was for a potato cannon instead of a rocket. Still, it might be useful to compare notes

do you reckon you could make a baffles in the bottle while keeping it see through so you can demonstrate how a firearm suppressor works? It would be quite difficult but it would be awesome high speed footage

Thanks for the link from your sponsor. Seriously, I was searching for a good idea for Christmas, and this is going in the list! Also, I love this video!

I'd like to see this on one of those weird 3 liter bottles.

Excellent! Your true joy and excitement is contagious.

wow, that colour on the second flame is beautiful. the one that goes back into the bottle again. The initial cyan flame is pretty nice too

Mate, you're 100,000,000,000 ^ 100,000,000,000 more competent, experienced, interesting and humble than the majority of so-called, self-professed "science" channels on YT. Same applies to Destin @ Smarter :)

Brother, your videos are really unique and slow motion is seriously satisfying. Greatly educational

That footage is GORGEOUS!

Fantastic video! I can't wait to see what your further experimentation shows!

This is so much fun!!!!!!

The flame front is a beautiful thing. I can't wait to see one of these fly.

Havent watched one of your videos in absolutely ages! The nostalgia is real

I finally got a notification from youtube again and started watching your older videos as well. I got the idea: can you do this with wood gas as well? It'd be really fun to see some of your projects combined!

dude i love this type of video! the whole process of your testing 😎 more like this!

It's funny how you're mostly composed and calm, but in this one you can feel the excitement :D It's great!

Thank you so much for the absolute joy you have brought me through the years ☺️ you are one of the reasons I am who I am today! Keep on experimenting!!

Awesome slo-mo shots! Thanks for the video.

A couple years back I built a propane torch pop gun based on your project. I used it as a prop for my Tusken Raider Halloween costume, and it's pretty much the only diy science project I had seen all the way through in a long time. Looks like I need to get back into this stuff again, thanks for making videos!

Such a great video and stunning shots!

Always bringing the best visuals. Awesome

The best youtube videos are made when the youtuber is enjoying what they re doing in the video. This is one of those times! great video!

I love seeing you get excited with each result. Such genuine happiness in your work. Keep it up! One safety tip I’d give is have an old table cloth or towel hung in the path the projectile is flying so it will hit that vs the wall. That should distribute the energy so the object will be less likely to bounce back at you.

The ignition point being at the very end of the bottle and the highly vigorous ignition shows precisely why gun barrels work so well and why bullet casings are designed the way they are with their primers.

Amazing that you are back!!
