Togher N.S.

We put soil in a pot. We poured water into the soil.
We put a glass into the middle of the soil.
We covered the pot in cling wrap. We put a pebble on top of the cling wrap directly over the glass.
We put the pot outside in the sun. The water evaporated onto the
Cling wrap.
Because the stone was in the middle the water dripped into the glass.
