Fun with Polyethylene Glycol

The host of The Action Lab makes entertainment out of the properties of Polyethylene Glycol. It's a substance made of long stringy molecules that cohere so well that they defy gravity. A good basic video of this property is at Geeks Are Sexy. In this later video, he tests those properties in Robert Boyle's self flowing flask. Can he make a perpetual motion machine out of the goop and the flask? Well, perpetual motion devices have enemies: inertia, gravity, air, friction, and some other laws that creep in if you ever defeat the big four. Polyethylene Glycol is no miracle substance, unless you're severely constipated.
