Instead of directly coupling the shock wave from the exploding wire (as the bridgewire does), the expanding plasma from an explosion of a metal foil drives another thin plastic or metal foil called a "flyer" or a "slapper" across a gap, and its high-velocity impact on an explosive (for example, PETN or hexanitrostilbene) then delivers the ...
Tannerite is a brand of binary explosive targets used for firearms practice and sold in kit form. [1] [2] The targets comprise a combination of oxidizers and a fuel, primarily aluminium powder, that is supplied as two separate components that are mixed by the user.
A new development is a slapper detonator, which uses thin plates accelerated by an electrically exploded wire or foil to deliver the initial shock. It is in use in some modern weapons systems. A variant of this concept is used in mining operations, when the foil is exploded by a laser pulse delivered to the foil by optical fiber.
Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length. [14] Aluminium foil is also used for barbecuing delicate foods. [15] As with all metallic items, aluminium foil reacts to being placed in a microwave oven.
A microwave oven uses a partial Faraday shield (on five of its interior six sides) and a partial Faraday cage, consisting of a wire mesh, on the sixth side (the transparent window), to contain the electromagnetic energy within the oven and to protect the user from exposure to microwave radiation.

The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
In 2022, about 11% of items the company delivered were shipped without the signature Amazon-branded box and instead came in their original containers, according to Amazon’s sustainability report.
The hot foil trick is a magic trick in which the magician places a small piece of tin or aluminium foil in a volunteer's hand, and the foil begins to rapidly increase in temperature until the volunteer has to drop it to avoid scalding their hand, and the foil is reduced to ashes on the ground.
