• This demo works best with small groups as the effect is short lived and visible only at close range.
• Wear cryo gloves at all times during the performance of this
  demo.
• Fill small styrofoam cooler (top photo) with liquid nitrogen to a depth of 5 or 6 inches. Submerge magnet in LN2 to cool down. When magnet reaches temperature of LN2, boiling becomes less rapid (may take 2 or 3 minutes). If magnet is not sufficiently cold, LOx will evaporate before suspension can be observed.
• 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 magnet’s variable gap.

Location

• Aluminum can, clamp, and magnet located in L01, section B2.
  Styrofoam cooler and ring stand in L34.
