In the ongoing saga of designing siphons for making layered drinks, we have previously presented the Mk II mini siphon for making two-layer shots, which works quite well. However, the nature of the self-starting siphon means that the volume of each pour is fixed.
But what if there were a way to modify the volume of the pour so a three-layer shot could be made?
Since our previous attempts at 3D printing a siphon to make a layered beverage, there have many advancements in the world of 3D printing, the most significant of which is the release of the Prusa XL with its multiple print heads. So, we figured it was high time to try printing some new siphons with newer technologies.
Here we try to make a new, hopefully better, version of the mini siphon for making layered shots.
After a longer than expected delay, MazeCubeGenerator now has the ability to produce 3D models that should be easier to print on a typical 3D printer.
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?
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?
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!
After the somewhat embarrassing failure of our first Black and Tan siphon, a second attempt looked much more promising. But would it actually 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.
