We really like screwing the bottles into one another. It cuts down on a lot of evaporation and when bottles get jostled, they remain chained together, preventing dripping on the floor. The chains of bottles help stabilize the system.

However, we are at a loss for how to tell people to cut through the ends of the 1.5 Liter Poland Springs/DeerPark/Ozarka water bottles. Screwing the bottles together requires getting that hole to be just the right size– 1″ diameter.

The plastic is very thick at that point. Here’s what we have tried:

1) Drilling using various bits: spade/paddle bit ($5),

2) Heating a 1″ Outside diameter cylinder. Sitting the bottle bottom on top of it until it burn through.

Criteria for a good solution:

1) Cheap

2) Safe

3) The tool is small and light so it could fit in kit packaging.

Ideas?
