Test-firing a liquid nitrogen cannon at the "Physics test range" near the Miller Observatory. The liquid nitrogen boils until the plastic soda bottle explodes. The two frames above are separated by 1/15 of a second, and the cannon tube is about two meters long. The projectile is a baseball.

Kenyon Physics student Alex Eversmeyer prepares for launch at the "Physics test range."
