Desert Day / Solar Still Survival Challenge

Solar Still Survival Challenge

Children build a solar still with a bowl and plastic wrap, discovering how the sun can help collect drinkable water.

How to run it

  1. Place a bowl of damp soil or water in a sunny spot with a small cup in the centre.
  2. Cover the bowl tightly with plastic wrap.
  3. Place a small stone in the middle so the wrap dips over the cup.
  4. Check after a few hours to see how much water has collected.
