After the success of the Mini Siphon Mk I, followed by the surprising failures of the full scale Beer Siphon Mk III, several changes have been made to the design to make it less fragile, less leaky, and hopefully just work. But would it produce a Black and Tan, or just more heartbreak?

3D Printing a Better Black and Tan Part 4: Revenge of The Supports
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?
3D Printing a Better Black and Tan Part 3: Giving It Another Shot
Our previous attempt to 3D print a self starting siphon for making a Black and Tan exposed a fundamental lack of understanding of fluid dynamics. But we decided to give it another shot!
3D Printing a Better Black and Tan Part 2: A Testable Prototype
After the somewhat embarrassing failure of our first Black and Tan siphon, a second attempt looked much more promising. But would it actually work?
3D Printing a Better Black and Tan, an Application of the Pythagoras Cup
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.
