"Looks like glaze you put on cake" I would have gone with something else but okay

Put tomato concentrate into the resin, then you can use the blood of your enemies as rocket fuel

"Don't smoke" he says while burning plastic in an enclosed space with no respirator xp

it's criminal how under-subscribed this channel is, he is like a mad rocket scientist from the movies. so glad youtube recommended this to me.

The most ballsy thing about these experiments is the lab location - under a wooden roof xD

Serious concerns alongside a video idea: ABS is extremely toxic when burnt. There's a reason why most commercial ABS printers are enclosed and why many people who print ABS encourage building printer enclosures. And that's just melting it. You're burning the ABS and that's releasing even more chemicals into the air. Secondly, I'm pretty sure that your current test stand has way too much friction and way too much mass. Though your printer's linear rail prevents more friction than is necessary within the context of a 3D printer, that's still a lot more friction than necessary. And your rocket mounting method (aka a huge, heavy clamp), means that the moving portion of your rocket has a lot of inertia to overcome in order to actually move. These two things together meant that you have a massive wall that your rockets have to pass in terms of force before any movement will be shown at all. If you were to build a system that has less mass on the movement axis and lubricated your rail or replaced it with something that moves smoother at lower forces, you'd see significantly more movement on your rocket tests and be able to judge differences in speed, etc. far more easily. Thus video idea: combine both of these. Build an outdoor test stand designed specifically for testing your rockets. I know you hinted at something like this in the video, but I think you could make an entire video re: your process of building a test stand that is safe (health wise), smooth (rail wise) and light (mass / intertia wise). And the result would also be better, more visual test results for the rest of your videos!

2:11 so close. Accidentally almost called them what they are - - Sparklers.

Me at the start of this video: Man he must have a special fire safe room for this testing Me at 11:06: Is that a wooden roof?

Align your rocket vertically with your rail. By keeping the rocket next to the rail you are actually producing torque on rail because that thing wants to spin.

"Sparkler" is the sparkly thing you put on birthday cake. love the video

"those things you put on birthday cakes" are actually called sparklers and I have never seen someone put them on a birthday cake, the're usually just waved around at event with fireworks such as fourth of july or sometimes a new years event

The editor version of you giving the other you in the past an idea is just glorious!

There are few ideas for improving hybrid rocket that I have. 1. You could incase whole solid fuel and nozzle in metal pipe of some sort, that would allow you to increase the chamber pressure that intern would speed up the exhaust gas that would produce more thrust. 2. If you know the energy density of your plastic filament and burn rate you can increase specific impulse (ISP) by controlling valves using Arduino and a stepper motor connected to the oxidiser valve. 3. You could make a nozzle from 3d printable ceramic resin, that would allow it to survive longer exposures to high temperatures and could be reused, also if the outer casing is made from steel pipe nozzle could be mounted on flex joints that allow it to gimble, but that is only after the problem of caring enough of oxidiser to power engine and also not too heavy for it to be able to lift off. Few tips that might help from my own research and experiences while I was active in our rocketry club before whole covid and all fun that came with it :D Use standard off the store pipe for the outer casing, you can easily drill through the end cap and fit nozzle and also use a high-temperature sealant for no high-temperature exhaust escaping around the nozzle and starting to eat solid fuel pellet/core. because we are engineering students we have all the tools like lathes and mills so it was a bit easier to weld and centre so we didn't have out of centre thrust. but you could also 3d print a centring guide for drilling in the centre of an end cap of the pipe. If you need help with calculations just send me a message on discord :) boksininkas_LTU [KARAS]#6196

might it be an idea to use a ball valve so that you can shut off the oxygen faster and you don't burn down your attic?🙃

As a type 1 diabetic the joke @ 4:32 was freaking hilarious! Thumbs up from me sir!

your channel has grown so much since i first started watching your videos! great video as always! keep up the amazing, unique work and high charisma

VI: try building a desktop fusion reactor Tomatoes are disgusting!

Love how this guy tries his best to make his videos funny and understandable by also trying his best at English. Keep up the good videos.
