Lemons Float, Limes Sink
It all has to do with density. It is just an odd thing about certain fruits, but it is science, and that makes it even cooler! Have you ever observed this phenomenon in real life? If not, you should try it next time you are out. All you have to do is ask for lemons in your water.
You can also ask for a side of limes and carry out a quick study. Technically you’d be conducting a real-life scientific experiment, which should make you feel even fancier. So, go forth, play with fruits, all in the name of well – science?
