Boiling stones, also known as boiling chips, are small, porous pieces of material used to promote even boiling and prevent bumping in liquids, particularly in chemistry labs. They work by providing nucleation sites for bubble formation, ensuring a more controlled and steady boiling process rather than a potentially violent eruption of vapor.

Deadpan, dry humour, or dry-wit humour is the deliberate display of emotional neutrality or no emotion, commonly as a form of comedic delivery to contrast with the ridiculousness or absurdity of the subject matter. The delivery is meant to be blunt, ironic, laconic, or apparently unintentional.
