Stupid Wizard Tricks: A Jar of Vacuum

[Aubri]

Suppose that you take a strong container -- a bell jar, for example -- and fill it with ectoplasm. Then you seal the container and allow the ectoplasm to dissipate. Since ectoplasm evaporates into "nothing", would you end up with a perfect vacuum?

You could probably do this with a simple air evocation.

That wouldn't be half as fun.
