• Drop a large NIB magnet on a thick copper plate cooled by LN and the magnet will bounce before coming in for a soft landing.
  • Copper plate takes ~20 minutes to chill out, LN must be replenished periodically.
  • LO will form on the top of the copper plate and be attracted to the magnet, so don't leave the magnet on the plate.
  • Lexan tube keeps magnet from going overboard when dropped from greater heights.
  • CAUTION: magnet is extremely strong.  Keep it away from ALL other ferromagnetic materials and erasable media, and put it back in its container when finished.

       (bring a full 4 L dewar)
       (LO is corrosive to an uncoated NIB)
