Sad accident happened:

17-year-old boy died in an explosion after flash paper from his family's online magic business ignited when he used hairspray on a 3D printer for a school art project.

Sixth Form pupil Tom Taylor used three canisters of hairspray to stick the piece of work to the hot plate of the printer after watching the technique online, an inquest heard.

An electric spark from either a nearby socket or the hot plate caused the hairspray gases, which had built up over several hours, to combust and ignite highly flammable flash papers that his family stored underneath the desk.An electric spark from either a nearby socket or the hot plate caused the hairspray gases, which had built up over several hours, to combust and ignite highly flammable flash papers that his family stored underneath the desk.

Many caused 3D printing general to be responsible for the case. Was it? Sure not.

How you teach your pupils doing nothing silly. Good question. Basics, or at least meaning of safety warnings on the side of the canister shall be part of basic education I do believe.

Anyway sad story with tragic ending.
