1 Put the bowl on a table/floor.
2 Put water in the bowl.
3 Put a mug inside the bowl .
4 Put the glad wrap over the bowl.
5 Use the string to tighten the glad wrap on to the bowl.
6 Leave the bowl buy the sun by a window/outside.
My prediction is that it will turn into a tiny cloud inside the bowl.
My prediction was incorrect.
The sun heated the water and it evaporated up towards the glad wrap.
Condensation formed on the glad wrap.When the water vapor became heavy it dropped into the cup,l ike rain. (precipitation)
