What you need to bring:

  • 2-3 bottle bottoms:  The bottom of wine bottles, beer bottles or thick glass bottles work well.  There shouldn’t be any huge dimples or divets in the bottom – just a nice flat chunky bottom.  If you don’t know how to break out the bottom – no worries – just bring the whole bottle!
  • Eye Protection:  Bring some protective eye wear.  If you don’t have goggles or shop glasses we’ve got some loaners just in case.
  • That’s it!  We’ll provide the rest!
