The Physics in the Field team of buskers pitch their tents at the festival in the Brecon Beacons, mid-Wales during 17-19 August. Over the course of the three days, they will perform eye-catching physics tricks to an unsuspecting audience.
Physics tricks are hand-held demonstrations using things you can find at home. Some are messy, some are noisy, but all of them are crowd pleasing and help illustrate different areas of physics. Festival-goers will also be encouraged to find out how to do the tricks themselves and give on-the-spot performances to their friends and families.
“It’s brilliant working with the festival goers because they are really interested in what we are doing and want to find out more,” said Liz Jeavans, outreach officer at the Institute of Physics. “What is really satisfying is when you show someone a trick, and they relate it to something they have come across in everyday life – but just hadn’t thought of it as physics before.”
The buskers are also performing two short physics shows during the festival. “Music to your ears” uses sound demonstrations to explain how some of those spectacular music effects are achieved. The second show is “Seeing is believing” which looks at colours and illusions.
And for those festival-goers who can’t get enough, all the tricks performed by the team, including making balloon kebabs, launching Alka Seltzer rockets or turning pints of water upside down over a friend’s head without drenching them, are available on www.physics.org with full explanations.
The shows and tricks are not just for young children, as the buskers will be making every effort to get adults involved as well. “We know that once adults have a go at the tricks, they’re hooked and go on to tell their friends about them. This really helps us in our aim of taking physics to people who wouldn’t actively seek it out,” said Caitlin Watson, the Institute’s physics in society manager.
The final stop in the tour takes place the following weekend, when the team bring their roadshow to the Newcastle Mela (26-27 August).

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...
