Here's something fun and strange you can do together while you're home.
Apparently, people over 40 years old can't hear this "nails on chalkboard" sound.
We tested it out at my house, I could hear it and it was not nice. My mom thought I was lying, or making it up as she heard nothing.
I decided when the kids came home to do a test to prove it to her. So we had the kids turn the opposite way, and close their eyes.
My mom had control of when she turned it on and off and the kids had to say when it came on/off.
She did, and they did and it proved that it was a real sound.
Can you hear it? Comment below and let us know!
