Magic Vacuum

A bottle that sucks all the magic out of the air around it. Depends on size of the bottle more than any magic applied to it, as the magic is universally applied to the bottle.

Within moments of opening, the bottle begins to work, though only magicians will be able to tell. All magic of all types will be pulled into the bottle. It will leak back out quickly if not corked, but if corked, will hold the magic almost indefinitely.

It will not come pouring out, it's more like putting air into a floatation device than a balloon.

It's a square meter of space per square centimeter in the glass bottle. It has to be glass, and it has to be treated with Eskaphus dust.
