    I'm a peroxide specialist, what you need is anaccelerant for the catalyst. You can try using some molybdate salt such as sodium molybdate and see if it makes a difference. Also you can try adding some low amounts of manganese dioxide suspended in solution. It's worth getting 50% peroxide since it's not as dangerous as what you created (which I think was grater than 60%). Peroxide reactivity somewhat increases exponentially as it gets concentrated. Also, make sure you are not using any metal firings, valvs, or parts at or near the peroxide tank. Your tank bursted because the peroxide you had concentreated was contaminated by dust and bugs, which then leads to it continuously releasing some oxygen, which then creates pressure build up in the tank, where the pressure then causes formation of heat and rise in temperature, which in turn makes the peroxide degradation faster and faster as this cycle continues = this reaction cycle was the cause for your explosion!
    I'd be happy to work together with you and recreate the devil's toothpaste, peroxide science and formulating with peroxide is my daily profession!

      In terms of safety, maybe some sort of thermometer or pressure gauge in the peroxide tank would be a good idea? That way you can catch the accelerating decomposition early and get clear.

    Devil's Toothpaste is really the same as the famous Elephant Toothpaste experiment, just executed with higher concentration hydrogen peroxide. In this case, [Integza] is using 50% hydrogen peroxide combined with potassium permanganate as a catalyst.

    I've worked with 90% peroxide and yeah, it can get pretty spicy. I never got any worse than a temporary white spot on my skin, though. I carefully avoided using catalysts of any sort and just treated it like any other rocket oxidizer and lit it off with a good spark-torch igniter, so you're on your own for making mere chemical reactions vs flames.

    7:15 This reminds me of the fueling process for the ME-163 Nazi Germanys rocket interceptor. One of the fuels for the rocket was so dangerous that it could dissolve a human. The fuels were T-Stoff (80 percent hydrogen peroxide and 20 percent water) and C-Stoff (hydrazine hydrate, methyl alcohol, and water). If I recall correctly when fueling one truck would pull up fuel then drive off and the second truck would then pull up to fuel the rocket. It was so that they didn't mix the fuels prematurely as contact with each other would ignite the fuel and explode.

    Ive been trying to get good peroxide reactions, for a monoprop rcs thruster, and what ive discovered is that most commercially available peroxides have stabilizing agents present that make it really hard for the peroxide to decompose, leading to a slower reaction rate. there is 2 work arounds i have found, 1. buy the proper stuff with no stabilizing agents, 2. (not as good but still effective) use potassium permanganate, this tends to react with the stabilizer, causing a faster reaction rate while also being one of the most effective catalysts out there.

    The yellow color of Mark's 2nd solutions could come from silver nanoparticles, which will significantly increase the speed of the reaction. You can also increase the pH of the hydrogen peroxide solution to make the reaction faster. Or, you can use warm solutions (NEVER heat 60% peroxide past warm to touch).

    Love how the first few minutes of the video are decoding a formula, hidden from you for safety reasons, for what we know to be a dangerous chemical, that could possibly be classified as a weapon.

    I should've guessed from the turning toys into death traps videos... but you're sounding a bit super-villainy in this; like Rober is your arch nemesis you're trying to take down.
    Keep up the good work!

    It's likely you are correct about the reaction between the more concentrated peroxide solution and the brass. High test peroxide was used as an ingredient in the propellant mixture used in some torpedoes from the late 40's until the end of the cold war. It is widely speculated that an HTP leak in the housing of a torpedo that was loaded into a brass lined launch tube was the cause of the Kursk disaster.

    "Concentrated hydrogen peroxide is like, rocket fuel!"
    And then he's surprised when his concentrated mix makes a lot of thrust and heat... like a rocket.
    (But yes this sounds similar to that steam rocket Integza made, based off the Me 163 Komet engine)
