I show you what happens if you try to focus a light down to a single point, then I show you how a laser is different due to population inversion.

,In this video I combine Robert Boyle's self flowing flask with Polyethylene Gycol, the self pouring or self siphoning liquid in order to attempt a perpetual motion flow system. I make the internet version of Boyle's flask to attempt this then I show the neat properties of the polyethylene glycol. Then talk about how perpetual motion is actually possible with superfluids.
