Nature's Bulb: The Firefly

A bulb turns electrical energy into light. Some creatures can make their own light using chemistry!
Nature's Equivalent:
A firefly or glow-worm uses a special chemical reaction inside its body to produce light. This is called 'bioluminescence' (which means 'living light'). They use it to talk to each other and attract a mate.
💡 Fun Facts
- Fireflies are super efficient! Unlike a light bulb, which wastes lots of energy as heat, a firefly's light is 'cold light' and wastes almost no energy.
- For a 'buzzer' equivalent, a rattlesnake has a special rattle on its tail, which it shakes to create a loud buzzing sound to warn off predators.
