The third live class from China's space station was held Wednesday afternoon, delivered by Shenzhou-14 crew members Chen Dong, Liu Yang, and Cai Xuzhe to students on Earth.

It is the first science lecture from the Wentian lab module. The previous two lectures of the "Tiangong Class" series were delivered by the Shenzhou-13 crew from the station's core module Tianhe.

The lecture content includes a capillary effect experiment, the vibration of liquid and liquid-solid mixtures, drinking water with a super-long straw, rotating and flipping wrenches, and introducing a plant growth study.
