7A70.26 - Straight Super Conductor Track
A small exportable straight Superconductor track.
The super conductor must be wrapped in paper towel so that one side is completely flat. It must then be wrapped in aluminum foil so the same side is flat. Holes are then carefully poked into the top of the aluminum foil to allow liquid nitrogen to get to the paper towel. This is then placed into the boat with the metal spacer placed on top.
