The idea behind this test is that a fresh egg will sink to the bottom of the glass, while an older egg will stand on its end or even float. This is because the air pocket inside the egg gets bigger as it ages, making it less dense than water. It's like a little egg experiment!
As the egg sits in the water, you can see if it's completely submerged, which means it's fresh. If it's tilted or floating, it's not as fresh, but still safe to eat. And if it shoots to the surface, well, it's probably time to say goodbye to that egg!
But why does this happen? It's all about the air sac inside the egg, which gets bigger as the egg ages. As the air sac grows, the egg becomes less dense, making it more likely to float. It's like the egg is growing older and wiser, but also less fresh!
