Testing for YBCO Supeconductor Quench via Magnetic Force
A YBCO superconductor is placed between the poles of a very uniform magnet and then cooled into its superconducting state. The field frozen into the sample at the state transition opposes the fringing fields on the magnet. However, had the magnetic field been strong enough to quench the superconductor, the results would have been the pendulum swinging freely beyond the pole pieces' diameter.

Acetylene Torch Not Lighting
The first shot at getting the torch lit and soldering. The flame kept going out because the nozzle was too dirty. The whistling at the end? That's my subconscious reaction when I'm thinking something might explode.

Superconductor Levitation in H Magnet
Here's what you'll see. As the field between the magnet poles is increased, the cylindrical superconductor which must have frozen in a bit of residual field when it was cooled will first orient it's magnetic moment perpendicular to the field to minimize the torque it feels. As the field strength is increased, the superconductor will then begin to move itself out of the magnet altogether eventually swinging off the screen. You'll also catch the odd snippet of extraneous lab conversations.

YBCO Superconductor acting as permanent magnet
Playing around with the superconductors on my last day in the lab. The superconductor was field cooled, (a fancy way of saying the permanent magnet was placed on top of the superconductor before liquid nitrogen was added.) The flux from the magnet penetrated the superconductor while it was in the normal state and was frozen in place once it entered the superconducting state. The result was that the superconductor behaves like a permanent magnet.
