Why it worked

The video leverages a surprising and slightly humorous fact about a well-known entity (NASA rockets) to capture attention, then provides a clear path for viewers to verify the information themselves, tapping into curiosity and a desire for knowledge.

Summary

The video explains that the core stage of NASA's Artemis SLS rocket shrinks by about 6 inches when loaded with liquid hydrogen fuel. The creator, an engineer who works on this, shows how this phenomenon can be researched on NASA's website.

Original caption

Did you know that the Core Stage of NASA’s Artemis SLS rocket shrivels or shrinks up by about 6 inches when very cold liquid hydrogen fuel is loaded into the tank? I help predict and estimate this behavior at work (Boeing builds the Core Stage), but you can also read about it online. Gotta love cryogenic shrinkage! I posted this two nights ago but I added more details this time. #nasa #engineering #shrinkage #artemisii #rocketscience
