What the laboratory scene shows
A boy on each side of the table helps with the experiment, and both wear short lab coats. The boy on the left holds a small container and touches the stopcock of a separatory funnel above an Erlenmeyer flask. Liquid drips into the flask, while the boy on the right holds a glass rod or pipette and watches the work.
Interesting facts about separating liquids
A separatory funnel is used when two liquids do not mix, much like oil and water. After the liquids settle into layers, the stopcock lets the lower layer leave the funnel in a controlled stream. Scientists label containers and observe each step carefully so substances are not confused.
