Who ever said that science is boring, probably never heard about density before. We all know that some objects can be the same size, but sometimes have different weights and this is because of their density. Well, liquids have density, too and you can exploit this fact to impress your friends by performing one really cool science experiment!
What do you think which liquid is the most dense: water, syrup or oil? Well, by pouring these three liquids into a glass you can see they clearly have different , densities, and form clear layers. Densest one should be at the bottom of the glass and the least dense will will float at the very top. Now, try dropping some items with different densities into the glass, and see the amazing result! Is this cool or not?
