The journey of Bob the Bubble proved to be a popular addition to my talk, raising a few chuckles (video below). Bob the Bubble illustrates the journey of a gas bubble from a magma chamber, through a conduit and the shape (morphology) transitions which may occur throughout ascent. As part of my talk I also performed a few short demonstration experiments (see photo) on the coalescence of smaller bubbles to make a cap bubble, through to an ascending slug. With the kind assistance of Tom Wilkes we even managed to demo a series of slug coalescence events which worked perfectly on the first try. This was rather fortuitous as it didn't really work during testing on the previous day!
Dr Ed Daw of LIGO heritage spoke after my talk and gave some fascinating insights into the science and what it really took to detect gravity waves! He also hinted that further discoveries may be coming soon...
A very enjoyable event which it was a pleasure to be a part of. A big up to all the volunteers who made this event happen in Sheffield!
