• A small fragment of combustible material burns when a piston is quickly compressed in an airtight cylinder.
  • Hold piston down for extended combustion.
  • For best visibility turn room lights off.
  • Cylinder must be thoroughly cleaned after each use, therefore multiple repetitions are time consuming.

        (use a 5 x 5 mm piece of tissue paper or equivalent piece of cotton fiber)
        (if piston rings are dry spread a thin layer of cooking oil on them)
        (thoroughly clean cylinder and store disassembled with o-rings protected)
