best demo competition 2025

Created by members, for members, the Best Demo competition is a celebration of exciting, entertaining, and share-worthy science demos. If there’s a STEM topic or phenomenon that gets you buzzing and you love showing it off to your peers, this is your moment.

The Best Demo Competition is all about passion and participation—not prestige. But within the BIG community, it’s one of the most coveted (and fun) ways to get involved.

This years' event took place on Thursday 16 July in the iconic Lecture Theatre at the Royal Institution and joint winners were Peter Gallivan and Kathryn Boast.
