To make this experiment you will need:
1. A bowl
2. A mug
3. Some glad rap
4. Some water
5. string/rubber band
1. Put the mug in the bowl.
2. Put the water half way to the mug but don't fill it.
3. Put the glad wrap on the bowl.
4. Seal it with the string or rubber band.
5. Put it in the sun.
My perdition was that the water will boil and the sun will make a sun beam but it would be all squiggly because of the water.
My perdition wasn't correct.
The results were that the sun heated up the water and evaporated up towards the glad wrap. Condensation formed on the glad wrap. When the water vapour became heavy it dropped water into the mug like rain (precipitation).
