SortStack #259 — 2027-02-23

By weight · Order from lightest to heaviest.

1. A standard steel paperclip 1 g

   During WWII, Norwegians wore paperclips on their lapels as a quiet symbol of resistance against occupation.

2. An iPhone 15 Pro 187 g

   Its titanium frame is the same alloy grade used in spacecraft and joint implants, trimming heft from earlier steel models.

3. A liter of water 1 kg

   The kilogram was originally defined in the 1790s as the mass of exactly this much water — the tie was only fully broken in 2019.

4. A whole pineapple 1.2 kg

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

5. An adult male white rhinoceros 2.3 t

   The 'white' is likely a mistranslation of the Dutch 'wijd', meaning wide — describing its broad, lawn-mowing mouth.

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.
