Thanks for pointing that out what I had overlooked – that I didn’t have any pictures or a clear explanation of the distiller!

I don’t have great pictures of how we did this, but this instructable does a pretty good job.

Basically, cut the bottle as you would for the filter, but instead of filling the top part with rice and sand, instead, fold the cut edge of the top part up, inside the bottle to create an internal trough to catch water. In the instructable, they placed this bent top piece on a black towel. In our example, we places it over the cut bottom part of the 2-liter bottle that held the filtered water.

Thanks again for the input and please let me know if you have any more questions!
