Sure! Here’s a brain teaser for you:

I speak without a mouth and hear without ears. I have no body, but I come alive with the wind. What am I?

Take your time to think about it, and when you’re ready, let me know your answer!

Solution: An echo. An echo is a sound that is reflected off a surface and heard again. It doesn’t have a mouth or ears, and it seems to come alive when the wind carries the sound waves.
