Bubble tea might seem simple, but those chewy tapioca pearls are doing something pretty remarkable.

In the latest episode of Chemists in the Kitchen, we head into the kitchen to break down the science behind boba—exploring how starch transforms under heat and pressure into that signature elastic texture. Along the way, we test the process, tweak conditions, and see how small changes can dramatically affect the final result.

It’s a hands-on look at how chemistry shows up in everyday foods—and how even a popular drink can double as a materials science experiment.
