Why Tall Buildings Do Not Fall Over
A tall building needs a wide, deep base. The base is called a foundation. It spreads the weight into the ground. Wind pushes hard on a tall building. Inside, a strong core of concrete runs from the bottom to the top like a spine. The core stops the building bending too far. The tallest buildings sway a little in strong wind. That is meant to happen. A building that could not bend at all would crack.

Bats
Bats are the only mammals that can fly. Their wings are made of thin skin stretched between long finger bones. Most bats come out at night. They find their way by making high squeaks. The squeaks bounce off things and come back. The bat listens to the echo and knows what is ahead. Many bats eat insects. One small bat can eat a thousand insects in a night.
