How to make a superior pooter
Making the holes just the right size for the nylon fittings was pretty easy with a step drill bit. These bits are costly so finding someone who has one you can use is a good idea. I discovered the friction from the step drill heated and stretched the plastic, resulting in some funny-looking cones in the shape of the bit. I had to cut these off with a utility knife. I kept trying the fitting as I ran the drill bit deeper since I didn't want a hole too large for the nylon threads to screw into. Once at the right size I screwed in the fittings and attached the vinyl tubing.
A short piece of tubing fit very nicely into the inside of the fitting in the bottom of the jar. I wanted this tube to prevent escapees. It does a good but not perfect job of it.
I found that the tubing was a bit to small to easily fit over the male end of the nylon fittings. I had to heat the very end in hot water to get it started onto the fitting. After heating the last inch or so in this fashion I found that the tubing was too limp to force on so I heated it in stages a quarter-inch at a time, alowing it to cool and retain its new larger diameter before dipping the next quarter-inch into hot water. With perserverance I got both longer tube lengths secured.
