The answers

If you’d rather play this day first, don’t look yet.

  1. Count · How many?

    How many tennis balls were there?

    Answer 33

    Counting one by one takes time: beyond about four items, each extra one adds a quarter to a third of a second.

  2. Tilt · What angle?

    How far is Mars's axis tilted?

    Answer 25.19°

    25.19°, close to the Earth's 23.44°: so Mars has seasons too, each about twice as long as ours.

  4. Hold · How long?

    Hold for one beat of the pendulum in Big Ben's clock tower.

    Answer 2.00 s

    2 seconds. Old pre-decimal pennies stacked on the pendulum keep the clock on time: each one makes it gain 0.4 seconds a day.
