lol That thing isn't a mouse, but liquid nitrogen solid oxygen (ice).
SpaceX was not leaking so where did the liquid nitrogen come from?
lol I meant liquid oxygen becoming solid.
A piece of solid oxygen ice that formed as the second stage Merlin engine vented liquid oxygen before ignition broke off from a vent and was caught by the exhaust gas manifold that surrounds the engine bell.
The same phenomenon has been seen in previous Falcon 9 launches.
And the same ridiculous claims have been made before by English tabloids and YouTube conspiracy mongers desperate for clicks.
