This week’s episode: September 28, 2018

Get ready to shine up those chompers! Students from the Indiana University School of Nursing visit to share tips on dental health. On this episode we do a really fun experiment you can try at home.


Stain an egg (hard-boil it first to make it less likely to crack while working with it). You can stain the egg with coffee, soda, fruit juice, even ketchup! Anything you can cover it with. Leave it for some time and then rinse it off… Gross! The egg is definitely not pretty and white anymore.


This is just like your teeth! Now, just like your teeth, put a bit of toothpaste on a brush and scrub that egg. Wow! It really works! Try this same experiment again and again changing the variables. Changing variables would be using with different methods of staining the egg, using different liquids or leaving it to soak in for different lengths of time. You can also do a comparison between toothbrushes and toothpastes, too!
