Cryo Test for Frost Formation on the Balloon Envelope

DESCRIPTION

Determine whether or not supercooled water will form frost on the plastic surface. Note that a 1964 ECOLE study determined that the material of the balloon envelope did not play a factor in frost formation. So we will use garbage bag plastic as an substitute for the balloon envelope.

OBJECTIVE

  1. Attempt to create supercooled water
  2. Usage of supercooled water to form mist inside cryo chamber

EQUIPMENT

  1. outfitted cryo chamber, including
    1. styrofoam dry ice reservoir
    2. mounted fan
    3. temperature sensor
    4. web portal that displays temperature readings
    5. 10 lbs dry ice (if there is not enough left in the styrofoam dry ice chamber to complete the experiment)
  2. dry ice handling gloves
  3. bottle of distilled water x 3
  4. 12” x 12” square of garbage bag plastic
