I am also a well-known professional science communicator, specialising in wonderful demonstrations with commonplace equipment. For indoor events, for example in cold weather, I bring along enough gear to amaze everyone for hours. There's almost no age limit to the appeal of these things. From six to ninety six, I guarantee to keep everyone fascinated with smoke-rings, colour-changing cabbage, gyroscopes, clouds in a bottle, Cartesian Divers, human circuits, electrostatic hovering poo-bags, paper plane catapults, exploding film pots, drinking straw squeakers, rocket balloons, singing wine glasses, banknote reaction tests, spinning-top circus, and of course my various bubble skills...
Seriously, I have performed my science shows to audiences all around the world: https://www.interactives.co.uk/#/science-shows/
