The Sacramento Section invited over 150 attendees at the annual CalEPA Earth Day Celebration to participate in an experiment demonstrating how CO2 absorption can increase acidity of the oceans. Kids and adults alike were amazed at the color change indicating a lower pH after blowing bubbles in a neutral solution with red cabbage pH indicator. The budding scientists were awarded stickers, mini-moles, tattoos and booklets with more cool experiments to do at home.
