    If you have a freeze dryer, you can take it one step further by making dehydrated instant water: carefully transfer the boiling water into the trays, then run the freeze dryer until all of the water has evaporated. Whatever is left is compact and easy to store, with a practically infinite shelf life. To turn it back into water, simply add water and stir thoroughly.

      You’re referring to the reverse mpemba effect? The mpemba effect is already controversial, and the reverse effect is just theoretical from what i understand, being either too weak to be measured or just not real

      It also does not require the water to have been boiled prior, and if the water is frozen it would be slower than liquid water regardless

        No, I’m referring to the tceffe abmepm. The water molecules “remember what it “felt like”” to be boiling so they are faster to return to that state the second time. It is really real.
