After the successful test of a miniature siphon for making layered shots, it was time to try a full sized siphon for making a Black and Tan. But will it work?
The Black and Tan (or Half and Half in some countries) is a fascinating beverage, and an excellent demonstration of density stratification in fluids. Recently we have started to explore the possibility of using 3D printing to create a device that can make a Black and Tan by displacing a less dense beer with a denser one using a siphon rather than the traditional method of carefully pouring the less dense beer on top of the denser beer.
Having recently been March 17th, which is essentially Irish-beer awareness day, we decided to test if we could tell the difference between Guinness draught in the can (with a widget) and in a bottle (nitrogenated, but without a widget).
It is our blog’s fledgling anniversary, so we wanted to celebrate. With beer. And Science.
What happens when you’ve run one too many oceanography demos and like beer? This:
