It's a shit title because the video us actually about metallurgy and thermite welding, not track expansion and contraction.
I imagine this guy watching a vsauce video going "oh god there's so much irrelevant shit". I like that these videos are about being curious about one thing and discovering other things for it, rather than being about learninga single fact.
He probably just noticed this amazing video that is about what the title says - https://youtu.be/zqmOSMAtadc
(It's Practical Engineering).
woah it goes on and on for 16 minutes just to say because strain? pssh, I could've watched 4000 tiktoks in that time all split between someone saying half a sentence with "wait for it" messages to keep me invested in the second half at the top and subway runner at the bottom
I'm subscribed, when the video came out something along those lines was the title. They likely changed it because it performed better with viewers.
He has a video from a while back where he gets into how he does A/B testing with titles and thumbnails. TL;DR click bait titles and thumbnails work.
it's a good hook because I always thought they were supposed to have gaps
