Fresh Water
From salt water comes fresh water
Materials you will need:
• Salt
• Water
• Tablespoon
• Large bowl
• Small glass
• Saran wrap/cling film
• Sunny Day
Steps:
1. Use a large (preferably clear) bowl and fill it with water.
2. Stir in several table spoons of salt until it has dissolved.
3. Place the empty glass (small)in the middle of the large bowl.
4. Cover the large bowl completely with the saran wrap so that no air can pass through.
5. Leave the bowl in the sunlight for a few days and watch to see what happens.The heat from the Sun should form water vapour from the salt water in the large bowl on the under side of the saran wrap/cling film. The vapour then condenses on the saran wrap/cling film which happens to be colder and drips as fresh water into the small glass in the middle of the bowl. There shouldn't be any salt in the middle glass.
