Took another virtual class today. Chemistry: Fireworks, Forensics, and Fun with a teacher named Phil Cook who is also called "Tik Tok's Favorite Chemistry Teacher."
He used a lot of big scientific words so I didn't understand a lot of it. But I thought it was cool that you could try to figure out how fireworks work. This slide explains what makes a firework.
In the next section he talked about what makes rockets go. He talked about propellants and explosives. Explosions are caused by chemical reactions that happen quickly.
The next section was pretty cool. He talked about how different chemicals create different colors.
He had a whole row of chemicals and lit each of them on fire so you can see what color they become.
The last part of the class was also pretty cool. He had three rockets with different chemicals and we were supposed to guess what kind of spark it would make.
The middle one, which was magnesium had the biggest spark.
Here's the link to the full video.
