Summary
Contrary to what your local magician might tell you, things cannot appear out of nowhere! In this BrainPOP movie, Tim and Moby will teach you all about the law of conservation of mass! You'll discover why the law is used and how it's used in practical terms. Find out the different parts of a chemical reaction and who first realized that in a closed system matter can be neither created nor destroyed. Plus, you'll see an example of how the law works. Unless you know something we don't, don't expect to find any bunnies under top hats anytime soon!
