Match lift
It is simple,
using air, to lift matches from the table into their box. Hold the case between
your lips and lower it over the matches. Draw a deep breath, and the matches
hang on to the bottom of the case as though they were stuck on. By drawing in
breath you produce a dilution of the air, in the case. Air pressure pushes the
matches from underneath towards the opening. Even a single match can be raised
in this way, if the air is drawn in sharply.
