I want to use piranha solution to kill a large, horrible thing that I really don't like.
quickly running away, because, to paraphrase a certain god of blood and war, piranha solution cares not from who the flesh melts off of, only that it does
Additionally, it is highly unsafe to mix quickly. To quote piranha solution's Wikipedia page:
Piranha solution should always be prepared by adding hydrogen peroxide to sulfuric acid slowly, never in reverse order. This minimises [sic] the concentration of hydrogen peroxide during the mixing process, helping to reduce instantaneous heat generation and explosion risk. Mixing the solution is an extremely exothermic process. If the solution is made rapidly, it will instantly boil, releasing large amounts of corrosive fumes. Even when made with care, the resulting heat can easily bring the solution temperature above 100 °C. It must be allowed to cool reasonably before it is used. A sudden increase in temperature can also lead to a violent boiling of the extremely acidic solution.
As such, I want it to mix only at the instant it arrives on-target - preferably F̴͝ͅÃ̵͍R̶̻̓ away from me. Essentially, I will keep the sulfuric acid and the hydrogen peroxide separate for as long as possible.
The question: how do I:
- (A) ensure that the sulfuric acid and hydrogen peroxide only mix once they arrive at the target
- (B) minimize the risk of the sulfuric acid and hydrogen peroxide mixing before they arrive at the target
Bonus points for coming up with a method that lets them mix quickly, so that the target gets to deal with a violent exothermic reaction/explosion as well as the nightmarishly corrosive fumes.
Extra bonus points for making its delivery method some kind of human-portable weapon, such as a grenade or a sprayer.
