This might be one of the best chances to both listen to AND experience chemistry at the same time. Grab a bath bomb, fill up the tub, and let's find out how these friendly bombs work. How do they fizz up? How do they suddenly smell? Where do the colors come from? Can they make bath scientifically better? Let's hop in.
We have a very special guest this month, Stephanie Ryan Ph.D. aka @letslearnaboutscience (on Instagram)! Stephanie leads us through some cool experiments you can do at home using vinegar and baking soda. Be sure to check Stephanie out on Instagram, and look for her book "Let's Learn About Chemistry" wherever you buy your books!
Wow sunglasses sure are cool. What's the coolest thing about them? Is it how cool they make us look and feel? Or is it the chemistry inside them? We'll let you decide, but we think you'll be surprised to find out how significant a role chemistry plays in the making of your shades.
