This ingenious product was designed by vaporizer pioneer Eagle Bill. The "shake and vape" method is based on a practice of the ancient Egyptians. They used hot stones to vaporize herbs at the right temperature.
To use the Eagle Bill:
Remove the gauze.
Put your finely ground herb in the pipe bowl and place the gauze back in the same place.
Heat the bottom of the pipe until vapor appears. To get more vapor you can gently shake the pipe.
