Trezzie, the mermaid is back for another science adventure. This time Fig teachers her how to make a magnifying glass with a few drops of water.

Trezzie collects things people leave on the shore of the lake. People think these things are trash, but Trezzie knows they are treasures. In this adventure she makes good use of an empty fruit box. Trezzie has found rocks with patterns on them. She shows them to her friends. Fig shows Trezzie how to make a magnifying glass with water and the plastic fruit box. Now they can all see that the pattern is a fossil. Trezzie has found trilobites.
