ROUND 1
Road Bicycle — 1.8 m
Answer: a road bicycle measures 1.8 m (length / span), which is about 1.1× smaller than the reference, a Velociraptor at 2 m.
A road bike’s wheelbase is barely a metre; the wheels themselves add the rest.
Common miss: players tend to inflate a road bicycle when it sits beside a Velociraptor — big things get squeezed, small familiar things get stretched.
Answer: a New York subway car measures 18.3 m (length / span), which is 1.5× as big as the reference, a Tyrannosaurus rex at 12.3 m.
A common New York subway car is about 60 feet long.
Common miss: players tend to compress a New York subway car when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: a rescue helicopter measures 17.8 m (length / span), which is 1.7× as big as the reference, an American school bus at 10.7 m.
Most of the length is tail boom — the cabin itself is barely longer than a van.
Common miss: players tend to compress a rescue helicopter when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
Answer: a high-speed train measures 200 m (length / span), which is 1.1× as big as the reference, the Roman Colosseum at 189 m.
A complete high-speed trainset can be around 200 metres long.
Common miss: players tend to compress a high-speed train when it sits beside the Roman Colosseum — big things get squeezed, small familiar things get stretched.
