ELI5: Explain Like I'm 5


Blimps are really big balloons filled with air or gas. They are similar to an airship but aren't as fancy. Instead of having an engine like airplanes do, blimps are pushed by the wind. When the pilot wants to fly higher or lower, they let more air in or out of the blimp. People use blimps for advertising and to give people rides in the sky. Many people think they look cool!
