Today's class focused on the most exciting part of Chemistry: Reactions! We started out slow, cleaning dirty pennies with salt and vinegar. We then got some bubbles going with three different baking soda experiments: Hidden Gems, Floating Glove, and Citrus Explosions. Next, things really got going when yeast and hydrogen peroxide combined to make Elephant Toothpaste! And the big finale was supposed to be amazing when Mentos were added to Diet Coke - but the Mentos jammed up in the tube after only one or two were added and a very minor reaction resulted. Oh well, we will just have to keep experimenting! Pictures are below! Enjoy!
