Pint-sized Physics and Qr Codes

50,000 beer mats will be making their way to upwards of 70 pubs around the UK starting, Monday 10 December. They are being distributed by local branches of the Campaign for Real Ale, CAMRA, who are supporting the campaign.

There are three designs of beer mat that each focus on a different aspect of the physics of your pint. Scanning a QR code on the back of the mat will reveal the answer to the question, as well as an explanation of the physics that makes it that way.

The answers to the questions can be found at, which serves as a hub of information on the topic, providing links to further articles about beer and physics on topics such as the true colour of foam.
