    "Fabrication.
    In a similar fashion to those described above, place
    the hydrochloric acid in a bottle with aluminum foil. Then, seal the bottle.
    Chemical Reactions.
    Meyer (2005) describes this reaction as
    Al (s) + 2HCl (aq)

    AlCl (aq) + H

    Aluminum Hydrochloric
    acid
    Aluminum
    chloride
    Hydrogen
    The aluminum and hydrochloric acid react to produce aluminum chloride and
    hydrogen"

    • The chemistry explanation:  The aluminum foil in your kitchen is coated with a type of wax.  This is to prevent you from being burned by the aluminum since it is a strong skin irritant.  The Works toilet bowl cleaner (and some others) contains hydrochloric acid.  The acid strips the coating away, exposing the aluminum.  Hydrochloric acid reacts rapidly with aluminum to produce Aluminum Chloride (soluble) and Hydrogen gas.  Here’s the reaction (omitting key steps needed to get the reaction to work):

       

      6HCl(aq) + 2Al(s) –> 2AlCl3(aq) + 3H2(g)

    • Bottle bombs" (also commonly known as "Drano bombs" or "works bombs") are not a new phenomenon; they've been a favorite of youthful pranksters for decades, as their construction requires only a few ordinary, commonly available components: plastic soda bottles, aluminum foil, and Drano (or other brand of household drain or toilet cleaner). In general, one need simply push some aluminum foil balls into a plastic bottle, add some Drano, and screw the cap tightly onto the bottle. The combination of the hydrogen chloride or sodium hydroxide in the fluid and the aluminum foil creates a strong chemical reaction which releases hydrogen gas; when that gas builds up to sufficient pressure, it ruptures the side of the plastic bottle, releasing the contents in an explosive burst:
    • It's a hoax. Gets tossed around every few years.

       The postings do inspire a few kids here and there to try it. And a few dads for that matter.
    • If one was so inclined, dry ice would give you the same effect without the toxic/flammable side effects...
    • Bottle bombs containing Drano and water are showing up in people's yards, and yes they are quite real.  These devices consist of a plastic bottle, Drano, water and aluminum foil. Other versions can contain baking soda and vinegar. When the aluminum foil comes into contact with the solution a strong chemical reaction occurs, releasing a gas which causes pressure to build up inside the plastic bottle, which eventually explodes. And boom, if you pick it up when it explodes, it can cause severe burns.
