This is what happened when the BBC Bang Goes The Theory roadshow hit See Further: The Festival of Science + Arts with their interactive area and hourly stage shows.
In the interactive area, the BBC Bang Goes The Theory team brought a wide range of interactives, experiments, and demonstrations - including their famous coffee-powered car.
Check out the photo gallery and this audio report for a flavour of what was there:
Taking a step into the BBC One: Bang Goes The Theory stage show in Purcell Room at Queen Elizabeth Hall was a diverse audience. Ages ranged from two to sixty nine years old and teachers, school children and the public packed the auditorium.
From exploding potato-firing sniper weapons to death defying feats of underwater swimming, the show was packed with fun and excitement for all the family. The interactive performance blended live experiments with scientific facts, video clips and historical figures.
A famous experiment by the 16th century scientist Galileo was performed on stage. Does a bottle filled with coloured liquid fall to the ground at the same time as an empty bottle? Yes - gravity accelerates everything to the earth at the same rate.
Audience participation allowed some great observations of the experiments. One child accurately predicted: "A flat piece of paper will have more air resistance." That’s why the ball of screwed up paper falls to the ground quicker.
The show finale was a gruesome demonstration of the effect on our brains of removing pressure. A doll’s head placed in a bell jar oozed foam from the ears, nose and mouth. However this would only be a problem for an astronaut if the pressure suit failed on the edge of space.
This performance with Dallas Campbell was part of See Further: The Festival of Science + Arts.
