Dyslexic-ally read the title as “What makes Weird Al So Weird, Good and Evil” and am now disappointed.

I look forward to metal foam I-beams. Imagine nearly the same structural integrity with a tenth (or less!) of the weight.

does the air stay trapped when submerged at any depth of water? Would it work say 100 meters under the ocean?

I don’t understand. In the video he clearly makes an argument for not using horns in cars.. Basically saying: “you wouldn’t do this while walking, so why in a car?”.

Just spent the last 4 days in NYC and while car horns in the city are to be expected, the situations in which they were being used were ridiculous.

Do you know what I do when the plane lands? Nothing. I sit there and relax while all the busy bees trip over themselves and get angry and work their blood pressure up trying to get two minutes ahead of each other, and when they’ve finished I leisurely stand up, grab my things, and saunter casually off.
