Physics and Harry Potter cloaks…

I was puttering through my feeds and found this gem:

Phys.org’s take on invisibility cloaks

This particular article says that moving thousands of meter’s per second will ruin the effect of being invisible.  Harry & friends probably didn’t suffer much from that, unless they were on broomsticks.  This article is probably addressing the affects that planes and jets have to deal with…still funny it’s to read it 🙂
