“Science After Dark: Wizards, Muggles and Science was an event hosted by the Museum of Discovery. During these monthly events, museum staff members conduct educational, science experiments for the attendees’ entertainment. The video shows the final experiment of combining liquid Nitrogen with hot water to create a reaction. The resulting explosion was of surprising magnitude, blowing off the safety masks of both demonstrators, damaging tubing from another exhibit near the ceiling, and a portion of the inner barrel was hurled upwards landing on the railing near the ceiling. Nearby audience members were sprinkled with condensation from the experiment. No one was injured. The staff conducting the experiment looked very surprised by the magnitude of the reaction.”
