Summary

Concrete is so much more than just a sidewalk. We use it to build playgrounds and skateparks and even musical instruments! But how does it go from a powder to a sludge to the strong building material that we use all over the world? And can we come up with new recipes that are better for the environment? To celebrate this superlative substance, Molly and cohost Mark are joined by special guest Concreature, a being from the concrete dimension! Tune in for a dose of history, some magnificent moss, and some hot, hot science. See omnystudio.com/listener for privacy information.
