How dirty is a drink cup?

The video taps into a common curiosity about hygiene in public spaces, using a simple, visual science experiment to provide a tangible answer. The relatable subject matter and clear, concise presentation make it easily shareable and engaging.

The video demonstrates a science experiment to test the bacterial contamination on a self-serve drink cup and its lid. A swab from the cup and lid is used to inoculate nutrient agar plates, which are then incubated for 24 hours. The results show a fair smattering of skin bacteria on the cup and a more significant amount on the lid, described as common and not too terrible.
