What you need
Two small plastic bottles
Drinking water at room temperature
A breezy day*
*On a still day, you’ll just have to wait a bit longer.
Fill both bottles with room-temperature drinking water.
Wrap one of the bottles in two layers of kitchen paper, holding it in place with sticky tape. Wet the paper with water.
Put both bottles outside in a breezy spot and leave them for 25 minutes before drinking.*
