- | - Place a small piece of flammable material((brown paper towels bought in stores work, cotton balls work best. The greater the surface area-to-mass ratio, the better.)) in the glass tube by unscrewing the bottom platform. You can also drop it into the top and use a ramrod to push it down. | + | - Place a small piece of flammable material((brown paper towels bought in stores work, cotton balls work best.

- Before screwing the platform back, ensure the piston/plunger is at the top of the cylinder (The ideal spot is marked with a line), then screw the platform back while holding the plunger at the line. | - Before screwing the platform back, ensure the piston/plunger is at the top of the cylinder (The ideal spot is marked with a line), then screw the platform back while holding the plunger at the line. | ||
