"Teetertotter Wall"

Ronald Rael, an architecture professor at the University of California, Berkeley, and Virginia San Fratello, an assistant professor at San José State University in California created seesaws at the United States-Mexico border wall to allow children in both countries to play with each other. The "Teetertotter Wall" was installed in Sunland Park, New Mexico, where a slatted border fence separates it from Ciudad Juárez, Mexico.
