One of the purest forms of entertainment around today.

  1. Think of a time, for example, 1 second.
  2. Start stopwatch
  3. Excitedly watch digits count up to chosen time.
  4. When you think the digits are on chosen time, hit stop.
  5. Give yourself a pat on the back if spot-on.
  6. Repeat.

N.B. - This works best if you are a schoolchild in the 90s with one of them there fancy calculator / stopwatch / calendar watches. That may or may not also tell the time.

You've all done it, don't smirk.
