De-Erickious Dumas, a seventh-grader at Hilsman Middle School, reaches out to touch a carbon dioxide bubble generated by mixing dry ice and warm water. The bubble was part of a demonstration showing that carbon dioxide is heavier than air during the first Bioenergy Day at the State Botanical Garden, sponsored by the UGA Bioenergy Systems Research Institute in October.
