This was an investigation about a mystery gas's flammability and density! We've been investigating the mysterious gas that emerges from bath bombs. This picture is us testing two properties of gases, density and flammability, to help us identify the unknown substance. 

The student, Josh Shope, is holding the flask containing the mystery gas. He is about to release the gas into the air and identify if it puts out a flame above it or below it, this will help us determine the gases density as well as flammability. I hope this  description is helpful! I also have more pictures of multiple classes doing this investigation!
