Why would I think of making this? Look carefully in the flames, you will find something.
Yes, we are doing a science experiment in science class. There was a balloon filled with Lithium gas and one of our classmates volunteered to burn the balloon with a long stick with fire on its end. And then...
The balloon popped and exploded.
The reason why our classmate looked so calm is that the explosion just happened and no one had reacted to it yet.
This is the full video of what happened in Chemistry class. Enjoy.
