ROUND 1
American Football — 28 cm
Answer: an American football measures 28 cm (length / span), which is 1.2× as big as the reference, an NBA basketball at 24.3 cm.
An American football is measured along its long axis; the pointed ends make it read larger than it is.
Common miss: players tend to compress an American football when it sits beside an NBA basketball — big things get squeezed, small familiar things get stretched.
Answer: a bowling ball measures 21.8 cm (length / span), which is about 1.3× smaller than the reference, an American football at 28 cm.
Every bowling ball is the same width — only the weight changes, from six to sixteen pounds.
Common miss: players tend to inflate a bowling ball when it sits beside an American football — big things get squeezed, small familiar things get stretched.
