A spark on a spark plug Lightning is a natural example of an electric spark. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized , electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.

Microwave-specific effects tend not to be controversial and invoke "conventional" explanations (i.e. kinetic effects) for the observed effects. [19] Non-thermal microwave effects have been proposed in order to explain unusual observations in microwave chemistry. As the name suggests, the effects are supposed not to require the transfer of ...
6. Nachos. Microwaving nachos can leave the chips soft and the cheese rubbery. Instead, reheat them in the oven. Arrange the nachos on a baking sheet, sprinkle on some fresh cheese, and warm at a ...
“Never microwave a hard-boiled egg,” Amanda Holtzer, a registered dietitian in Nutley, New Jersey told Fox News Digital. “Doing so causes steam and pressure to build in the egg white — and ...
Triboluminescence of nicotine L-salicylate. Triboluminescence is a phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed (see tribology).
Microwave ovens operate by emitting electromagnetic waves, particularly microwaves, which interact with water molecules in the food. These microwaves cause the water molecules to oscillate rapidly ...
The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its ...
