  • Hey, I’m a chemist, and you’re getting some bad info from others in this thread.

    Hydrogen peroxide decays into oxygen (and water) by itself over time, and certain things can speed that process up. What you’re seeing is oxygen bubbles that have been trapped by the soap.

    Oxygen isn’t itself flammable, so trying to light those bubbles probably won’t do anything. You’d need to add some sort of fuel to the bubbles. I’ve seen hydrogen gas bubbled through soapy water and lit, and that is definitely exciting.

    The mixture you’ve made is sort of on the way towards sodium percarbonate. You could get that more directly with some oxiclean (or a generic alternative). Probably won’t bubble because the peroxide is sort of locked up as part of the percarbonate, but it’ll still do its oxidizing thing. Oxidizing the chemicals that are a part of skunk odor makes them no longer smell.

    Don’t use oxiclean or its equivalents on pets. Your best bet there is soap, water, and time.











  • It’s why so many of the DC stuff is so boring. These are superpowers that have minimum viable characters wrapped around them. The only interesting thing that can happen to them is changing their powers.

    I watched this movie, and they really tried to make it interesting. She starts as a total screwup and arcs towards greatness. But none of the motivation makes any sense and so most of her decisions come down to “if she didn’t do this the plot wouldn’t move forward.” Frankly, that’s how almost every superhero movie feels now.

    I think the problem with this movie is that a) it wasn’t for kids and b) it wasn’t for manchildren who wear clothes with Batman logos on them. Not a lot of market left after that.





  • A lot of the early (1789) revolutionaries were from the nobility and even the clergy. Many of the reactionaries were up and coming bourgeois who were about to make their way into the nobility. Sorry Marx, you got a few things right, but that one was an oversimplification.

    The vast majority of the victims of the reign of terror were commoners. The nobility were underrepresented at the guillotine, besides a few obvious high-profile cases.

    It appears as though Robespierre legitimately lost his mind at some point. He attempted to introduce a “cult of the supreme being” with himself as high priest that focused on adhering to his own idea of virtue. Anyone not virtuous enough, which was effectively literally everyone else, was liable to be executed.

    Early in the revolutionary wars, the revolutionaries had arrested so many people that the Paris jails were super overcrowded. Some people didn’t want the armies to leave Paris for the front lines because maybe all those jailed people would break out and cause trouble. So Marat proposed that they reduce the incarcerated population… by killing them all. September 1789 was a bad month to have been a petty thief in Paris.

    So many of the popular notions about the revolution are distorted or just ass-backwards.
