Donal Vaughan returns to Fringe with his lab coat and a gadget table, using his trademark joviality to impart serious scientific knowledge to crowds of spellbound children.

Dealing in centrifugal forces, air pressure puns, and the practical everyday science of zombie protection, the show boasts an array of gadgets, made by the man himself. For example, a specific contraption made out of laundry items captures attention of the audience, who are undoubtedly keen to replicate the content of the show at home. Vaughn does include appropriate safety warnings and conceals the identity of specific objects in order to prevent the repeatability of his more dangerous stunts.

Vaughan connects with his audience using humour, mostly of the toilet variety, which is slightly rude, but nothing too crude. He shares entertaining childhood anecdotes and imparts random snippets of tongue-in-cheek life advice. This example of standup-meets-science education combines physics with toilet humour in all the right ways.

From exciting moments with a plasma ball to the mechanics of a spun gun, this hilarious romp through the universe of solids, liquids, and farts is engaging, educational and, above all, entertaining.
