They folded a scaled-down version of the origami plane and placed it into the Kashiwa Hypersonic and High Enthalpy Wind Tunnel in Tokyo. Then they blasted it with Mach 7 winds — over 1,000 meters per second — for seven seconds straight.

Why does it feel like a "hold my beer" moment?

Randall Munroe talked about something similar in his book how to, the conclusion for a paper envelope was basically: if it's slow enough to not burn up, then there's a pretty large range of places where it could land. And then other random objects: If it's aerodynamic enough to go somewhat fast, and there's no heat shield, it's probably going to burn up.

:D

Maybe I am not cultured enough: can someone explain the hold my beer joke?

IIRC, you are like 14-ish y/o, so give it a few years before you say "Hold my beer" and jump off a building with only an umbrella as a parachute...

almost 14 yes (shudder, I will be... old... (joking)) - but it's good to know about more stuff either way!
Don't worry, will not be attempting not anytime soon

I just can't help but wonder how this passed peer review in an actual journal. It's a fun exercise, but contributes nothing to the field.
