Rheology at Playwrights Horizons

Has anyone seen this?  Running now through May 29. 

In Rheology, Shayok Misha Chowdhury joins forces with his physicist mother, Bulbul Chakraborty. Bulbul is obsessed with the mystery of sand: how it flows like a liquid, but then jams into a solid. Misha is obsessed with his mother. But they’re running out of time. In this boundary-pushing collaboration, an artist son and his scientist mother challenge each other to a high-stakes experiment.
