We run free monthly ‘jam’ performances, as well as improv shows at various festivals. Sign up to our mailing list to stay in the loop about our upcoming events!

Upcoming performances

After our sold-out launch show, we are excited to announce that our show SPONTANEOUS REACTIONS will now be happening monthly this summer! Join us at 8pm at the Boathouse Pub on Chesterton Road, on Thursday July 21st, August 4th or September 1st!

Each show we’ll have a different special guest scientist join us onstage, who will bedazzle us with a short talk about their research, thus inspiring a set of improvised scenes and montages, which will be sure to enlighten and entertain…

This show is suitable for an adult audience. Tickets are £8 (general), £6 (concession), and are available on Eventbrite.


Following the success of our sold-out show at the Cambridge Science Festival last year, we are bringing our unique blend of science and improv to the masses with improv jam-sessions or ‘jams’ every month! Get your FREE ticket to our next one on Eventbrite! Jam-sessions are more relaxed than shows, and if you have some previous improv experience you can join us on stage as a performer – get in touch if you’re interested! Our events are suitable for an adult audience. Please bring a face covering unless you are exempt.
