Egg On My Face

There's never been a smarter way to eat the best meal of the day. Dual holder readies one below. Dishwasher safe glass is 4" high, 2 1/2" diameter. $1.99

Alright, I'll admit that I need help with this one. How does this work? Do you take the scalding hot egg out of the pot and try to get it under the glass on the bottom? And why would you do this? And won't the boiling hot egg on the bottom eventually ruin my vinyl tablecloth? And why not just use two next to each other?
