Bumping is a process in which a solvent becomes superheated and then undergoes a sudden release of a large vapor bubble, explosively forcing liquid outside of a flask.

You may have tried using boiling chips in organic chemistry lab during a distillation experiment. Boiling chips are made of a porous material and have a nonreactive Teflon coating - they provide nucleation sites (extremely localized budding for gaseous bubbles) so the liquid boils smoothly/more easily. The air bubbles break the surface tension of the liquid being heated and prevent superheating and bumping.

An ebulliator can also be lowered into a distillation flask to introduce small air bubbles - this serves the same function as boiling chips.

In chemistry, bumping refers to the sudden and violent ejection of liquid from a container when it is being heated. This can occur if the liquid is superheated and suddenly begins to boil, causing splattering and potential hazards if not managed properly. It is important to use caution and proper techniques to avoid bumping during heating.
