Science videos are pretty cool, so I was excited to see this cool one using soap bubbles to show how a fluid infused with a magnetic material would flow through the bubbles interstices...
... until I watched to the very end and then decided this was actually some weird horror movie trailer. Still, way cool, and the editing was very good.
But man, those last few seconds are creepy. Funny how we anthropomorphize things, or at least mentally give them a vitality they really lack.
