The place where the world comes together in honesty and mirth. Windmills Tilted, Scared Cows Butchered, Lies Skewered on the Lance of Reality ... or something to that effect.

Having 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?
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. But it can be fun to play with.
