Mechanochemistry is a reaction enabled by the use of mechanical force. A greener solution that is better for the environment, mechanochemistry allows us to produce chemical reactions without using harmful solvents. But what exactly is mechanochemistry? And are there any real-world examples that come close to explaining the process?

About the Series

Science at Home is a family-friendly digital program that looks at the history of scientific discoveries through the lens of a hands-on activity that families can do together at home. Sessions are prerecorded using storytelling to introduce a science topic and connect it to an at-home activity. This program series combines history, science, and fun, while highlighting the stories we tell and the collections we house in our museum.
