    Can I use this to quickly apply regular toothpaste to my toothbrush?
  • Very cool mate!! Great to see that porous ceramic catalyst working as well as it did!
  • "It might explode or it might work really well." Spoken like a true rocket scientist.
  • @Weisz
    I really didn’t think the devils toothpaste recipe would have been so simple, dang. Super cool video!
  • Video Idea: now that you have higher a working rocket of sorts, make a big one with multiple output nozzles, or a multi stage rocket! Tomatoes are disgusting!! 🍅
  • For a video idea, saturate your ceramic blocks with silver (colloidal silver?) instead. This is what is used in jetpacks. It flashes to steam and doesn't have the nastiness that elephant toothpaste does as it flashes to pure steam.
  • @jnplnrvl9581
    the porous ceramic part was such a genius idea.
  • @PlasmaChannel
    But did this Devil's toothpaste go down to Georgia, Tomato lord? Or shall I say Rocket Lord?
  • This is essentially how the classic jetpack works. They use a high concentration hydrogen peroxide with a silver or platinum mesh screen as a catalyst to instantly vaporize the H2O2 into steam.
  • @AkrimaSablosang
    one thing I love is that, the more Integza progresses, the less his engines look like modded water bottle, as they take a much more legit and pro look.
  • @zeekjones1
    That sludge at the end can be used to line the edges of the reaction chamber, just like a sugar rocket. Leaving a hole through the center going straight to the nozzle from the peroxide injector. The nozzle is honestly optional with the sheer pressure coming out; bigger exit, less explosion, more retrys.
  • @InservioLetum
    Mark Rober is literally a rocket engineer. He would have absolutely no problem getting his hands on PURE peroxide, as this is in fact a rocket fuel type still in use today. A very FUN fuel type in fact.
  • @jtwarner13
    With your CNC skills improving, you should revisit some of your Tesla projects using more and more metal parts! It would be cool to see the turbines last longer.
  • Video idea: attach something like an afterburner to the back of the nozzle so that you can use the oxygen from the reaction to boost some type of combustion, maybe even add alcohol in the acid to ignite it in the first chamber.

    As someone who knew very little about rocketry when I started watching your channel, it's exciting to see the progression of your rocket designs! Can't wait to see the next iteration of your devil's toothpaste rocket, or DTR, which given the initials I think you should henceforth refer to as Dietrich.
