Acidic Ocean Experiment

Adventures of Ed the Bear did an awesome experiment to demonstrate what would happen if acidity in the ocean got out of hand, due to fossil fuels and global warming. "Acid oceans are caused by increased amounts of carbon dioxide absorbed by oceans, putting many marine animals in danger." - Adventures of Ed the Bear 

materials:
2 jars (one filled with vinegar, the other water)
