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.
NDT: The N-Dimensional Ray-Tracer
Today we are proud to announce the release of the hyper-dimensional ray-tracer, ndt. Have you ever wondered what four, five, or even 100-dimensional space would look like if you happened to find yourself in it. Well, wonder no longer! Now you can see for yourself what it would be like to visit such strange higher dimensional spaces.
Triangle Testing: A Detailed Procedure for Blind Taste Tests of Beverages
From time to time we plan on performing a form of taste test, called a triangle test. What follows is the basic framework that will be used in those future tests.
On π-er dimensions
Rather than deliver yet another π/pie pun based post for π Day, we decided to take a more geometric approach. This time looking at something completely different, yet still round. One might even say, hyper-round.
Lime Juice vs The Margarita
In honor of National Margarita Day, we decided to do science to margaritas. We actually did this science last year, but apparently never finished this post.
Prototyping an election night drink: The Clinton
Having previously developed a theme drink to represent Trump for election night. This week we plan on calibrating the ratios of ingredients for a drink to represent Clinton.
Prototyping an election night drink: The Trump MKII
This presidential election cycle we are attempting to design two theme drinks that will be consumed on election night. Last week we determined the ratio of primary ingredients. This week we tested possible methods for giving the drink a frothy head to represent Trump’s trademark hair.
Prototyping an election night drink: The Trump
Here at Doing Science to Stuff headquarters we are quite fond of themed drinks. For presidential elections we like to make two drinks, one for each candidate. We then take a sip from the appropriate candidate’s drink whenever a state is called for that candidate. While we have a couple basic recipes in mind, there are some parameters that need to be fine tuned. In this installment we will be optimizing a ratio of ingredients for the drink to represent Donald Trump.
