Dental Hygiene student experiment shows effect of cola vs. water on egg shells

A photo showing the results of an "eggs-periment" from KCC Dental Hygiene student Lauren Rubley, who soaked the egg on the left in water and the egg on the right in cola for two hours. The lines on the egg on the right are from Rubley wiping the egg with a cloth to dry it off -- the cloth took part of the shell's surface with it.

Second-year Kellogg Community College Dental Hygiene student Lauren Rubley, president of KCC’s Class of 2016 Student American Dental Hygienists’ Association (SADHA), posted the above photo on Facebook last month highlighting an awesome “eggs-periment” she conducted in preparation for an oral health presentation to a class of 5-year-olds.

Rubley soaked the egg on the left in water and the egg on the right in cola for two hours. The lines on the egg on the right are from Rubley wiping the egg with a cloth to dry it off — and the cloth took part of the shell’s surface with it.

From Rubley: “Think about that every time you’re sipping on a cola throughout the day.” Yikes!

Thanks to Lauren for sharing her story and photo!
