I can't think of a good topic for an informative speech. I've tried a few different ideas but they were too boring. I want something entertaining so I will be more comfortable about speaking and have fun with it.

It needs to be something I can research and have a visual aid (can be pretty much anything--a Powerpoint, poster, object, etc.) for.

Help! I've been stuck on finding a topic all weekend and need to have it ready by Wednesday. Thanks in advance for any ideas.
