A thigh -
high glass barrier keeps people a safe distance from «North, East, South, West,» but Dia: Beacon is allowing in visitors over 18, a few at a time.
Innovative viewing platforms allow visitors to get close to the giant relics, often without
any glass barriers in between.
Somewhat curiously, however, it did so without any fanfare, with Audi quietly placing it near an R8 Spyder at its stand with nary a mention of the car's special nature other than
the glass barrier that surrounds it.
I found myself artfully dragging my lightsabers against
the glass barriers while slicing down blocks, and feeling the rumble of what my brain plausibly accepted as an energy beam slicing through anything and everything.
In the earth's atmosphere there is
no glass barrier and the gasses expand and rise until they cool.
