Exploring Science with Water and Maps

Mercy hosts a science show answering questions about leveling a fish tank and Earth's curvature. She demonstrates how to make a carpenter's level using simple materials and explains the concept of Earth's roundness through historical cartography. The show concludes with a practical demonstration of creating a flat map from a balloon globe, illustrating the challenges of representing a spherical Earth on a flat surface.
