Paramagnetism of Liquid Oxygen

• This demo works best with small groups, as it's a little bit messy and the effect is short lived and visible only at close range.
• Wear cryo gloves at all times during the performance of this demo (no brainer).
• Fill small styrofoam cooler (upper left photo) with liquid nitrogen to a depth of 4 or 5 inches. Dip magnet into LN2 to cool it down (if magnet is not sufficiently cold, LOx will evaporate too quickly upon contact to produce effect). Using a paper cup, remove some LN2 from styrofoam cooler and pour into suspended can. Liquid oxygen will condense on surface of can and drip into the magnet's variable gap.
• Aluminum can, clamp, and magnet located in L01, section B2. Styrofoam cooler and ring stand in L34.
