On October 11th, Lamont held its annual Open House, during which our doors were open to the public. Most labs or research group put together a booth or presentation to highlight what they do as well as entertain/educate our guests. Despite the rain, we had a huge turn out this year. In the Rock Mechanics lab we had a constant stream of excited kids and adults come enjoy our presentation called "Bending, Sliding, Cracking, Squeezing Rocks".
Heather demonstrated reaction driven cracking with a piece of calcium oxide submerged in water.
Hannah discussed similar cracking occurring over longer time scales in expanding mortar within cored sandstone...
…and in naturally occurring peridotite samples.
