Fun Fact Friday, Number Twenty-Three!

This week’s fact comes under the category of “Science.”  Do you happen to know the source of the bubbles in champagne?  No, it is not carbon dioxide.

The short answer: dirt, dust, or lint!

The longer answer: carbon dioxide molecules would evaporate without something causing the bubbles to form.  This something was originally believed to be the slight imperfections with the very glass itself.  However, it has since been discovered that the bubbles form on microscopic particles of dust/dirt within the glass which act as condensation nuclei for the dissolved carbon dioxide.

Who knew!  Even straight out of the dishwasher, my glasses are filthy!
