Rolling in Fun: 8 Fascinating Facts About Cylindrical Wonders You Never Knew!

1. Propane Cylinder Recycling Woes

If you thought recycling was a total gas, think again: Empty propane cylinders shouldn't be placed in recycling bins, as they can wreak havoc for recycling facilities. Instead, return them to the point of purchase or seek out a household hazardous waste recycling program in your community, which may even sport biannual drop-off events for such items.

4. O'Neill Cylinder: Outer-space Living

Who needs Earth when you can live in an outer-space cylinder that's out of this world? It's like the International Space Station, but five thousand times cooler, and with room for a veggie garden: Enter the O'Neill cylinder, a proposed rotating space habitat with a 5-mile diameter and 20-mile length, boasting artificial gravity, climate control, and alternating land-windshield-window segments. This far-out abode, conjured by physicist Gerard K. O'Neill, would primarily use materials from the Moon or asteroids to offset building costs, potentially making it a comfortable, self-sustaining human living colony in the great cosmic beyond.

5. Majestic Columns: Architecture's Bodybuilders

Who needs six-pack abs when you can have majestic columns? Feast your eyes on the OG bodybuilders of architecture: Saskatoon's early buildings were adorned with Greek and Roman-inspired columns, featuring five distinct designs – Doric, Ionic, Corinthian, Tuscan, and Composite. Made mostly from Mediterranean marble, these bad boys held up more than just their fair share of admiration. But don't confuse them with their cylindrical cousins: Columns lend their strength to buildings, while the smooth-talking cylinders woo their way into a variety of roles, leaving them far from the architectural limelight.
