Part of my day at work is spent in the barrier, a germishly-free mouse facility.  To get there one has to change out of their clothes and into surgical scrubs, gown, gloves, bouf, shoe covers, etc.  My favorite part of the day is the entry once you are garbed through the air shower that blows air furiously at me for a minute or two while I hold my hands in the air.

I love this thing!  And I wonder if I could get one installed in my house? 

I close my eyes and pretend I am flying.  The simulation is very convincing.  Bonus it makes me laugh.
