Apparently this was never released on Quest 3. However, I’ve just found out that the fastboot command “oem set-sensorlock 1” enables Sensor Lock, and it works, even if your headset isn’t unlocked!

I was reminded recently of one of the more dumb-ass things I have done. In one of the Armadillo Aerospace vehicles we ran an alcohol feed pipe through a liquid oxygen tank. It had an air gap jacket, but we were still concerned about the possibility of freezing the alcohol if there was an extended launch hold. We did an experiment with a beaker full of ethanol in a liquid nitrogen bath, monitoring the temperature over time. The result was unexpected — the alcohol didn’t freeze solid, but it took on the consistency of a thick honey. We would pull the stir stick out and watch the viscous liquid slowly make its way down. It was so mesmerizing that I… poked it. With my finger. Liquid nitrogen is less dangerous than many people think — it isn’t like a Mr. Freeze gun. I had a high school science teacher that splashed some at students after doing the frozen flower demonstration. It flashes to gas and dissipates really quickly. This was like reverse napalm. Super cold, sticking to my finger, and not evaporating or sliding away. It was just a tiny drop, but it was instantly obvious I had made a mistake. Only a tiny little patch of frostbite resulted, but it did drive a bit more caution later.

Emergent Thinking. That's the skill I lack.
