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.
After a long day of searching for yooperlite, it can be hard to put the blacklight flashlight away, and you may find yourself running around a dark house shining ultraviolet (UV) light onto random objects, making surprise observations.
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.
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).
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.
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.
Just a quick post to wish people a Happy New Year and to report on a mini measurement!
