It's time to question everything you know about science. Just kidding, but we will be talking about the phlogiston theory. This was a 18th century scientific theory that scientists used to explain combustion. Thanks to the discovery of oxygen, we now use the oxygen theory to explain combustion, but we could always be one discovery away from a new scientific revolution. Thanks for watching and keep it science-y!

A clarification correction for everyone: When I talk about a balloon filled with air as seemingly lighter than an empty balloon I meant to say that the balloon was filled with hydrogen or helium which are lighter than the standard air.
