Heh.

It actually is for real. What's not obvious is that they're
not "cutting" the glass. They're chipping it.

The scissors are chipping bits off the edge. The water is there
to deaden the shock and thereby prevent the rest of the glass
from shattering.

Stained glass artisans do the same thing using glass nibblers,
but those don't need water, because they're taking off such
small pieces.

You can't cut through the middle of a sheet of glass using
that method. Cutting with scissors requires that the cut
material has to bend. Glass won't bend enough - it'll break
first.

Except when in a near molten state - some glassblowers _do_ use
"scissors".
