  2. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    Piranha solution should never be disposed of with organic solvents (e.g. in waste solvent carboys), as this will cause a violent reaction and a substantial explosion, and any aqueous waste container containing even a weak or depleted piranha solution should be labelled appropriately to prevent this.

  3. Thermite - Wikipedia

    en.wikipedia.org/wiki/Thermite

    Use of match heads enveloped with aluminum foil and a sufficiently long viscofuse/electric match leading to the match heads is possible. [ citation needed ] Similarly, finely powdered thermite can be ignited by a flint spark lighter , as the sparks are burning metal (in this case, the highly reactive rare-earth metals lanthanum and cerium ). [ 37 ]

    Americans have been using aluminum foil for over 100 years, since it was first used to wrap Life Savers, candy bars, and gum. ... this shouldn’t be a problem, as the amount of aluminum that is ...

  5. Microwave burn - Wikipedia

    en.wikipedia.org/wiki/Microwave_burn

    The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...

  6. Intelligent banknote neutralisation system - Wikipedia

    en.wikipedia.org/wiki/Intelligent_banknote...

    The chemical reaction causing the explosion of the pack and the release of the dye creates high temperatures of about 200 °C (400 °F) which further discourages a criminal from touching the pack or removing it from the bag or getaway vehicle. [5] Dye packs are used to foil robberies in over 75% of banks in the U.S. [5]

    Just crumple a handful of aluminum foil, add the usual soap, and that burnt food will scrub off just as easily. Just avoid using this on non-stick surfaces that might scratch.

  8. Reactive multi-layer foil - Wikipedia

    en.wikipedia.org/wiki/Reactive_multi-layer_foil

    The foil can be used as a pyrotechnic heat source, a replacement of potassium chlorate/iron pellets, for thermal batteries. It reacts faster than the conventional composition, reaches higher temperatures, and heat buffers of inert metal (e.g. steel) are needed to lower the peak temperature and prolong the heat delivery. [7]

  9. Aluminium alloy inclusions - Wikipedia

    en.wikipedia.org/wiki/Aluminium_alloy_inclusions

    Inclusions can create problems in the casting when they are large and in too high concentration. Here are examples of problems related to inclusions: Pinholes in light gauge foil; Flange cracks in beverage containers; Surface streaks in bright automotive trim and lithographic material; Breakage in wire drawing operation; Increased tool wear and ...
