Why it worked
This video likely performed well due to its relatable and educational content for young children, focusing on a common daily habit (hand washing) presented in a fun and engaging way with the use of slime and popcorn.
Summary
Two children are shown with a large bucket of popcorn. One child has slime on their hands and is asked if they washed their hands. The children then go to a sink, and one child washes their hands with soap and water, drying them with a towel. They return to the popcorn and begin eating.
