How to Desalinate Seawater

I can't believe there's a whole ocean full of water but we can't use it.So here's a way to desalinate seawater.It is best to try it on a sunny day early at sunrise;it will be done more or less in the afternoon.

Use the big container and put the round black lid inside it.This is to atract sunlight.

Place the small cup in the middle of the container on the black lid.

Add some seawater that you want to desalinate in your container but don't spill it in your cup.

Put the plastic over the container and fasten it with your elastic band.

Add a small weight on the plastic right above the cup so that the plastic points down to your cup.

Wait for the water to evaporate, condensate on the plastic and trickle down and into the cup for you to drink.
