It's been a half an hour and the hand sanitizer is up to your
waist. Maybe you should re-do your calculations?
It took 15 minutes for the 18 inches of the room (1.5 feet)
to be buried in pink goo.
You don't want to be in the room if it is covered in 6 feet of
goo.
How long will it take for the room to be filled to 6 feet?
