Sparks, spinning and smoke wowed pupils at a special Mad Science day at Linton Heights Junior School on Thursday (June 18).

Mad scientist, Cosmic Karen, left students agape as they watched her make flaming paper vanish into thin air and turn candle light into dazzling refracted rainbows.

Year 4 pupil, Matthew Adcock, 9, could not decide which the coolest part of the workshop was.

“I can’t decide between the [burning] tissue paper and the bubbles with the dry ice,” he said.

Pupils learnt about refraction, forces and physical and chemical reactions in a special visit from Mad Science.

“I didn’t realise that when you change the centre of gravity [of an object] it changes the speed,” Matthew added.

Mad Science runs interactive learning experiences for children which provide entertainment as well as education.
