glad to see young folk getting into this. l'm 65 and did rocket back in the 60's when apollo was going

[@skyartrc8286]

I liked how you used a scale to measure the maximum thrust!, Great idea! I'll also give this a try, thanks!

[@HNXMedia]

Agreed! I am totally "borrowing" that idea. Will need to some math for proper calculations (with the scale I have) but that scale and test stand is what I call pure, cheap simplicity and I LOVE it!

They were not turned on though watch it again

[@terrycollins3954]

Always ready to be educated🤷‍♂️W😮W👍keep up the good work

[@EricRobb]

Thanks So Much! I'm Glad you learned a lot. Have a great day.

[@Digitallifeconcepts]

So what kind of fuse did you use? Regular firework or could this be set up with an electric match like store bought ones? Great work. BTW

[@GOTHAM21]

There was drag from what the engine was taped to. Try taping a pvc tube like you had the engine, but now put the engine inside the pvc tube. Engine should be sitting inside the pvc tube loose. Now ignite it. Scale should indicate thrust more accurately now.

[@EricRobb]

Great idea! Thanks for the tip! Have a great day.

Did you print the nose cap

[@grayfog1307]

GUSY HELP!!! I live in europe and i cant get kmno3. Is there any solution for this??

[@Midnightrider773]

I hope 'Magic Bullet' is sponsoring your video 😄 awesome video

[@EricRobb]

I wish! Thanks for watching. Have a great day!!

[@dalemoolman3089]

Place a little cone shaped exhaust it builds up more thrust power i think 🤔

[@Deeseditz15]

Do you wash the grinder each time you grind one thing

[@EricRobb]

Not most of the time. The components being mixed together here are not volatile to be dangerous if you don’t wash between uses. Have a great day!!

[@johnny4498]

Could you use a laval nozzle with this like normal solid rocket engines use?

[@EricRobb]

The clay forms a nozzle so you don’t need an external nozzle. Have a great day!!

[@trident1409]

Won't the pvc cato ?

[@theaussienurseflipper.8113]

What's other people's videos and they seem to put it on heat and make it into putty, cheers Graham

[@kevinduprey9326]

Instead of tape, try using bungee cord to hold it secure.

[@camgonzalez2424]

You should link Grants video in the description

[@onthetrail3457]

Legal to make. Illegal to transport.

[@tzaylor]

Have you tried them on a rocket yet?

[@EricRobb]

Yep. ua-cam.com/video/oeaQMxhsh9E/v-deo.html

i love you

[@rishiparitala88]

What clay did you use?

[@EricRobb]

bentonite clay. I got it from Kitty Litter

[@rishiparitala88]

@@EricRobb Do you know any brand that sell kitty litter in small quantities

[@EricRobb]

@@rishiparitala88 I just bought a 7lb. bag at the dollar store for a few dollars.

Give us the deminsions

[@EricRobb]

What dimentions specifically?

[@TaliwhakerRotmg]

@@EricRobb deminsions, not dimensions...

No, my name isn’t glen. Why?

[@adeharris4457]

Copied off tkor could have gave a shout to him

[@EricRobb]

True. Tkor is great!! And he was such a smart man. I wasn’t trying to copy him for the views, but I just wanted to make my own rocket motors. Tkor came up with an amazing way to make them. Thanks for watching and have a great day!!

Why put music in videos? Like cmon we want to hear the damn thing

[@theaussienurseflipper.8113]

A lot UA-camr do the music. And everyone does not like it. And music anyway a lot louder than speaking. Which if U watching at night and Ur family asleep is very annoying
