SortStack #2240 — 2032-07-27

By weight · Order from lightest to heaviest.

1. An unfed female mosquito 2.5 mg

   After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

2. A one-euro coin 7.5 g

   Its two-metal design is not just style — the distinct layers give vending machines an electromagnetic signature to verify.

3. A full backyard barbecue propane tank 17 kg

   The familiar grill tank stores propane as a liquid; on a hot summer day the pressure inside can roughly triple.

4. An adult male Asian elephant 4 t

   You can tell it from its African cousin by the much smaller ears and the twin domes on its forehead.

5. Big Ben, the Great Bell of Westminster 13.8 t

   Big Ben is the bell, not the tower — and it cracked within months of entering service in 1859; the odd tone is the crack.

6. A fully loaded 18-wheeler semi-truck 36 t

   Fully loaded, a semi needs about 40% more stopping distance than a car — which is why truckers leave that gap you keep filling.
