    1. Use a metal straw to improve heat conduction.
    2. Increase the surface area and time for heat extraction to occur with extra loops in the water part (do they make metal silly straws?)
    3. Get really fancy and use a counterflow chiller: create a two layer straw, where tea goes through one layer while cold water goes through the other layer in the opposite direction (obviously with an outlet somewhere besides your teacup)







  • Computers are binary, yeah? So we have to represent fractional numbers with binary, too.

    In decimal, numbers past the decimal point are 10^-1, 10^-2, … etc. In binary, they’re 2^-1, 2^-2, …

    2^-1 is one half, so 0.1 in binary is 0.5 in decimal. 2^-2 is one quarter. 0.11 in binary is 0.75 in decimal. And of course you’ve got 0.01 = 0.25

    The problem comes when representing decimal numbers that don’t have neat binary representations. For instance, 0.1 in decimal is actually a repeating binary number: 0.0001100110011…
