Really what I wanted to say is “holy crap I can’t believe this works!”
Yes, as soon as I saw this astonishing feat of wonder on Chasing Cheerios I had to run down stairs and try it by myself. In fact, I left it there as I uploaded the pictures and published this post. I haven’t heard it fall yet. I’m going to try to not go back into the kitchen (because I have stupid squeaky floors) and see if it’s up in the morning.
