March 20th Show Cancelled (S4E6)

March 14, 2020

Due to the general concerns about the spread of Coronavirus we have lost our speaker and seen reduced demand for tickets.

In addition, due to the evolving advice on public gatherings and self-isolation, we cannot guarantee we can produce a show that is up to our usual standard.


This is the first show we’ve ever cancelled and it was a hard decision to make. 


We intend to run with our other shows provided the situation improves.


Please keep safe and well and here's Gloria Gaynor demonstrating a cool way of washing your hands - https://www.youtube.com/watch?v=gBDeTzFCKME

Andrea Gaxiola, Robotic Hydrogels: On The Road (S1E1)

January 19, 2020

On February 22nd, the troupe headed west down the M4 to perform with Bristol-based troupe Rising Ape Collective to put on a double-bill of science-inspired theatre.

We were joined by guest speaker Andrea Gaxiola who did a talk on robotic hydrogels.

The talk inspired the players to create a series of comedy sketches where we encountered a woman involved in a 70-year staring competition with her sentient jelly-bots; unloved waxworks at M. Tussaud's being turned into candles; and robots made from Angel Delight!

Check out the show on our Show Archive page.
