Day 18 ran from a Venus flytrap (13 cm) to a Formula 1 Car (5.6 m). The widest gap was round 4, Smartphone against Koala, at 5.4×; the closest call was round 1, Refrigerator against Motorcycle, only 1.3× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Refrigerator (family size) vs Motorcycle (Harley-Davidson Sportster)

    Motorcycle · reference · 2.2 m
    Refrigerator · true height · 1.75 m

    1.3× shorter than the motorcycle

    A family fridge-freezer stands about 1.75 m tall.

  2. ROUND 2

    Fire Hydrant vs Polar Bear (Male)

    Polar Bear · reference · 2.4 m
    Fire Hydrant · true height · 75 cm

    3.2× shorter than the polar bear

    A street fire hydrant is about 75 cm tall.

  3. ROUND 3

    Venus Flytrap (whole plant, diameter) vs Atlantic Puffin (bill to tail)

    Atlantic Puffin · reference · 30 cm
    Venus Flytrap · true diameter · 13 cm

    2.3× shorter than the Atlantic puffin

    A well-grown Venus flytrap reaches about 13 cm across — the whole plant, not a single trap.

  4. ROUND 4

    Smartphone (6.1-inch) vs Koala (large adult, head to rump)

    Koala · reference · 80 cm
    Smartphone · true height · 14.7 cm

  5. ROUND 5

    Formula 1 Car vs Komodo Dragon

    Komodo Dragon · reference · 3 m
    Formula 1 Car · true length · 5.6 m

    1.9× longer than the Komodo dragon

    A modern Formula 1 car is about 5.6 m long — a metre longer than a family saloon.
