Fun Fact: 96 Hours vs. the Antarctic Darkness
At the South Pole, the sun sets around the March equinox and doesn’t rise again until around the September equinox, roughly six months of polar night and twilight. By comparison, a 96 hour timer covers exactly four full days, less than 3% of that long Antarctic night.
Radon-222, a natural radioactive gas, has a half-life of about 3.8 days. This 96 hour timer gives you 4 hours, 19 minutes and 12 seconds more than that.
