Highlighting this tweet in particular:

> Here's a chunk of pyrolytic graphite on the same magnet with the same stick. Even with less density and more surface normal to field.... It doesn't lift off. If it's diamagnetism it's a fucking absurdly strong one

Her findings, and suggestions of manufacturing process improvements, are very interesting.

Seems silly to compare to that absolute chunk of pyrplytic graphite. Shouldn't it be a similar size spec?
AFAIK the chunk will levitate irrespective of size up to some maximum. Diamagnetism is a property of the material, not the shape.
