Hands-On Science at Lamont-Doherty

At Lamont-Doherty Earth Observatory’s Open House on Oct. 8 the motto of the day was, “Clean hands are not learning hands!” said seismologist Marc Spiegelman. The annual event is a day of free public lectures, demonstrations, hands-on workshops for kids and a chance for members of the community of all ages to learn directly from world-renowned researchers. The eruption seen here sent ping-pong balls flying to demonstrate the hurling power of volcanoes.
