Our first homemade still - trial-run getting ready for our co-op lesson on the water cycle, our water purification system, and the different phases of water. It isn't very efficient, but it has produced some water.
Later on we tried another method, reported online to have greater yields (reminiscent of a solar still only with a round-lidded pot). Use an inverted rounded lid to cover the pot (containing the initial aqueous solution). Boil the water and suspend the receiving container in a colander in the same pot (so as to keep the receiving container cooler than the boil below). Add ice to the top of the pot and voila! You have a nice much more efficient at-home still. Not as pretty as the contraption with straws, but much more reliable, unless one wants to invest in actual chemistry equipment (which would be super-awesome but expensive, and better used for more advanced chemistry lessons on distillation).
