Production
Equipment and Supplies
Tools Needed
Drill press
Laser printer
15/16" flat drill bit
Utility Knife
Supplies Needed
4" PVC tubing and 2 pair hinges
wood and hardware needed for mounting brace to your type of drillpress


8 1/2" x 11" all weather laser print labels for sticker

500 cc plastic water bottles. This size was used in the published trials. Several characteristics make the Metromint 500 cc mint water bottle a good choice. It is clear which makes it easier to see medicine in chamber. It has a smooth surface so that the sticker can be applied and is thicker and more durable than other brands. Metromint has recently agreed to doante clean empty bottles to this project. (Please contact Steve McCrosky if you wish to build spacers with these bottles.)
3/8" OD clear vinyl tubing
Panel fasteners (ITW Fastex Christmas Tree Clip, part number 354-125300-00.)
