The October 17, 2026 puzzle ran from a hockey puck at 7.6 cm to an Olympic swimming pool at 50 m — about 656× apart, drawing on sports. The pair furthest apart was round 4: a tennis racket is about 1.5× smaller than an acoustic guitar.
Answer: Hockey Puck — 7.6 cm. A hockey puck measures 7.6 cm (length / span), which is almost exactly the same size as the reference, an apple at 8 cm.
A regulation puck is exactly three inches across.
Common miss: players tend to inflate a hockey puck when it sits beside an apple — big things get squeezed, small familiar things get stretched.
Answer: Olympic Swimming Pool — 50 m. An Olympic swimming pool measures 50 m (length / span), which is about 1.4× smaller than the reference, a Boeing 747 at 70.7 m.
An Olympic pool is exactly 50 metres long.
Common miss: players tend to inflate an Olympic swimming pool when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
Answer: Baseball Bat — 86 cm. A baseball bat measures 86 cm (length / span), which is almost exactly the same size as the reference, a trombone at 90 cm.
A common adult bat is 34 inches long.
Common miss: players tend to inflate a baseball bat when it sits beside a trombone — big things get squeezed, small familiar things get stretched.
Answer: Tennis Racket — 68.5 cm. A tennis racket measures 68.5 cm (height), which is about 1.5× smaller than the reference, an acoustic guitar at 1 m.
The rules allow up to 73.7 cm, but almost every player uses something just under 69 cm.
Common miss: players tend to inflate a tennis racket when it sits beside an acoustic guitar — big things get squeezed, small familiar things get stretched.
Answer: NBA Basketball — 24.3 cm. An NBA basketball measures 24.3 cm (length / span), which is about 1.2× smaller than the reference, an American football at 28 cm.
An NBA ball is regulated by circumference, about 75 cm, which works out to just under 25 cm across.
Common miss: players tend to inflate an NBA basketball when it sits beside an American football — big things get squeezed, small familiar things get stretched.
