The experiment highlights one way the virus could rapidly spread on surfaces, though close contact with an infected person is the most common method of transmission.
"It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes," said the CDC. "This is not thought to be the main way the virus spreads, but we are still learning more about this virus."
Nicholls added that a more effective experiment would be to see the same scenario play out after the "infected" person washes their hands.
"So the general public gets some concept of the mechanism of how much the use of hand washing can actually reduce the transmission of potentially infectious material," Nicholls explained.
