    True. Don't mess with this stuff and wear eye and skin protection. But it does not dissolve the salts out of your eyes; it dissolves fats and oils (hence Drano dissolving the oils in your PVC piping and properties of bases and acids). I am not in chemistry, but Honor's Physical Science with Mr. Gearren sure beats the heck out of it. I'm not even to chemistry, and I'm building hydrocarbons, mole-mole equations, and complex chemical equations.

    If you get drano somewhere, pour acetic acid (vinegar) on it.

    (H)C2H3O2 + Na(OH) --> NaC2H3O2 + H2O

    Chemical equations sure are fun

    Also, just taking a ring of some sort to trap the Drano and something to catch the product would help the chemical reaction along.

    Won't cut a clean line through 1/8 inch aluminum. My tin snips barely cut plastic that thick.

    hmmm, that reminds me of my remake of the Hindenburg. I had some mylar shipped, made a blimp, put some Al in draino inside of a 2L bottle. i left the cap off and stuck the flattened blimp over the top. I taped it off and away it went, with a fuse. it was really cool.

    ^it was for a digital media final project and i had the video edited into a short Hindenburg newscast. there were no people in the foreground though

    oh and to the anodized Al Q: no the anodizing is a protective layer, you must react with Al. so scrape it off first.

    Yeah, the anodized layer is so thin you should be able to rub it off.

    its going to make hydrogen gas, but at the scale this is being done at... its not really a problem. i do way more dangerous stuff quite regularly in the chem lab. of course... you can solve this issue by putting an open flame near it so the gas burns off steadily instead of filling a room. thats always fun... you might have intermittent bangs happening, kind of like in shop class when the idiots are fiddling with the oxy-acetylene torches.

    one thing that might get in the way of this idea is the amount of drano you need. the reaction will only happen so long until the solution is saturated with Al(OH)3, and then you need to wash it off and put some more on. this may take a while.


    Sometimes you guys just plain scare the hell out of me. :p

    My god. Were not talking chemistry here were talking idiotcracy.

    Every heard of the Hindenburg?

    We used to take wine bottles fill them with water and lye and put balloons over
    . . and you would have a hydrogen balloon. . tape some long! paper towel to the balloon, lite it and let it go.

    Thank you Mr.Wizard.

    But as far as using it as a tool? You'd damn better be outside.

    Im guessing the drano has quite a low molarity, so after a few hours if it eats through the aluminum in a spot and the drano pooled on the aluminum... drains, do you plan on sitting there for the remaining time constantly pouring drano over the remaining aluminum?
    If you do try this I recomend having a razor blade to scrape the salt/excess drano off every 10 minutes or so and starting with a new splash.
    And maybe a long book or a season of your favorite TV show to help pass the time.

    Yeah. Just think of the sick acid-burn effects, though...
