Hot on the heels of the backwards-speaking teenager comes another youngster with an amazingly weird talent. This time, a girl sings ‘Twinkle, Twinkle, Little Star’ in its entirety with her mouth closed. Where do you find these people, internet?

At first, this young girl’s trick may not seem all that impressive. But try it yourself. It’s definitely not as easy as it looks. We got about halfway through before throwing in the towel.

How exactly does she pull off this amazing closed-mouth feat? Is she throwing her voice? Does she have a mini speaker hidden somewhere in her mouth? If anyone has an explanation for this odd (but impressive) trick, we’d like to hear it.
