When I was teaching 2nd grade in Siem Reap, Cambodia in 2023, my students and I took a field trip to APOPO, a school that trains rats how to smell for unexploded ordinance(UXO), landmines mostly left over from the Vietnam War, and yes there are still a lot in Cambodia and Laos! My students and I LOVED it! The rats were very friendly and we were able to hold them 🙂
