Electricity is too fast, let's use water instead!

We all know that computers use electricity to perform calculations. However, if you've taken an introductory computer science course, you might have heard this statement: "In fact, any material that can represent zero and one can be used for computation—even pipes could work." Now, Paulo Blikstein from MIT decided to test whether what the textbooks say is true. He planned to design a machine that uses "water" to perform computations. After numerous major failures involving leaks, being soaked multiple times (he emphasized this point), and long experiments, he successfully developed logic gates such as AND and XOR, and even managed to design the first practical water-based circuit: a 4-bit adder. We commend this Ph.D. candidate for his remarkable contribution and suggest to those of you who are eager to try, it’s best to develop your Water IIc in the bathroom.
