One of the purest forms of entertainment
- Think of a time, for example, 1 second.
- Start stopwatch
- Excitedly watch digits count up to chosen time.
- When you think the digits are on chosen time, hit stop.
- Give yourself a pat on the back if spot-on.
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.
