DIY Rocket Engines - Easy and Cheap!

Drones, crowd suppression devices, explosives, rockets. This guy is planning something big.

"Well, I wanted to find a better way to find and remove a splinter from my finger. After some research we decided to build our own MRI chamber, so I started to do research on it and it turns out that to generate magnetic resonance images you also need so-called Perchlorates, which is a chemical compound also found in the surface of Mars in rather large quantities. So we turned our anechoic chamber into an interplanetary spaceship. And that‘s why we launched a colony on Mars so I could take an MRI of my finger, which altogether is also cheaper than your regular MRI facilitated by the US health care system."

I would have paid to have a teacher like him in high school. An hour long video that seemed like 10 min. Thank you for your hard work!

As a Veteran Air Force Rocket Fuel Handler I found this video really fun to watch. I used to work with UMDH hydrazine and N2O4 nitrogen tetroxide. These were extremely dangerous and poisonous chemicals that we worked with in amounts in the tens of thousands of gallons. I would love to spend a day in this guys garage.

I’m almost 50 years old and it’s amazing how you have inspired me to take up chemistry as a hobby now at this stage in my life. Thank you and please keep them coming.

I watched this on Christmas Eve, and here in Sweden we give the gifts on this day, and this video was like a real good christmas gift. I was like a kid, "yes, yes, rockets! Yippie!!".

First recommendation of this channel for me, the algorithm has been sleeping on the job. Within two minutes I'm thinking "why am I not already subscribed to this guy?" Then he puts emphasis on safety, then he mentions Scott Manley. C'MON YOUTUBE, YOU HAD ONE JOB Anyway, subbed. Thanks.

This video was the same density of information as my university lectures have, except the topic is really interesting so watching through a whole hour is done with little effort. Kudos to you and your team!

This was phenomenal. The camera zoom and focus were great. This was an extremely professional video and incredibly informative!

I'm reasonably certain that I could follow your meticulous instruction over a radio...you're BRILLIANT at how you convey your subject matter! Thank you!

"it's nice to know you could" I loved that comment

I remember when I first found your channel, it was at the very beginning and immediately subscribed. I was so afraid you might not get traction and shut it down. I'm so grateful others have found as much value in your channel as I have.

Had fun with Estes rockets as a kid and later got my daughter into it as well, but my dad always used to say that he refilled his own rocket engines back in the day. Finally got to see what's involved. Thanks much.

Probably the most intuitive introduction to practical rocket science one could find online.

Yes! Great to see another long-form video from you guys!

I can't believe this video is more than an hour long.. It felt like ten minutes the way it just sucks up your attention. Absolutely amazing quality! If chemistry classes were like this in my high school I would have been a chemist right now.

Wow, this video was outstanding! Thank you so much for teaching us in such a great way. I love your meticulous explanations, your care in showing us every detail of the process, and your eloquency. Greetings from Germany :)

YouTube algorithms may not prefer your super detailed longer videos, but we do, thank you for putting us ahead. Respect..🙏

This channel has to be the best for us slightly unhinged nerds and geeks who just love to experiment. I've even done some of this stuff myself, but nowhere near as well! He's like the dad we all wanted growing up.

So informative, it was sad not really being taught chemistry and so much of the world being confusing early on. Amazing creators like you give so much understanding to the people in the world it's truly incredible.
