Ever heard of the silver egg illusion experiment????? This experiment has to be the easiest and quickest experiment ever! You could literally start and finish this whole experiment within like one minute to two minutes! So, if you haven't seen or heard of this experiment then keep scrolling down and I hope you enjoy going through this post!
So when you are burning the egg you'll realize that it will begin to have a black powdery substance on it called soot, and when you submerge the egg into water it will look silver/ transparent. This happens because soot and water don't go together, so what happens is that air gets trapped between the two making it look the way it does.
