By weight · Order from lightest to heaviest.

1. A common housefly 12 mg

   Houseflies beat their wings around 200 times per second, which produces their signature buzzing pitch near the note F.

2. A whole pineapple 1.2 kg

   Pineapples take nearly two years to grow, and each plant produces just one fruit at a time.

3. The FIFA World Cup Trophy 6.2 kg

   Winners only keep a gold-plated replica; the 18-karat original stays with FIFA and gets each champion engraved on its base.

4. A full-size kitchen refrigerator 135 kg

   Refrigeration changed cuisine more than almost any invention; Einstein even co-patented a fridge with no moving parts in 1930.

5. A Steinway concert grand piano 480 kg

   Each Steinway Model D takes about a year to build and contains over 12,000 individual parts.

6. The Liberty Bell 943 kg

   Its famous crack was widened on purpose — an 1846 repair meant to stop the fracture instead ruined the bell's tone for good.
