    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!

    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

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

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

    Do you wash the grinder each time you grind one thing

    • @EricRobb
      @EricRobb  Рік тому

      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!!

    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.

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

      @zdeneksurovec3204 In Czechia its probably easy (idk i dont live there) but i live in hungary, and i looked for the stump remover thing but in hungary there is no stuml remover. I looked for other solutions, but they were just some shitty fertilizers. So idk where to get pure KNO3.

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