COLUMBUS, Ohio (WCMH) — COSI has been training rats to play basketball for decades but to celebrate 40 years since those rats became hoops all-stars, they are now learning a new trick.

NBC4’s Monica Day got a demonstration of a skill used by rats in the African country of The Gambia to detect landmines, with COSI’s Laurie Miller using spices for the experiment.

There is also an adorable surprise at the end to show off the future of rat demonstrations at COSI.
