In New Mexico, two California professors installed a cross-border seesaw that fits through the steel slats separating the United States and Mexico. Architects and designers Ronald Rael and Virginia San Fratello came up with the idea way back in 2009.

The seesaws were installed on July 28, 2019, on the wall that separates Sunland Park, New Mexico, and Ciudad Juarez, Mexico. In an Instagram post, Rael said the event was "filled with joy, excitement, and togetherness at the border wall." He goes on to say, "Using the seesaw shows that we are equal and we can play together and enjoy ourselves, but also that the wall cuts the relationship between us. What happens in one place has an impact on the other and that's what a seesaw does."

The border has become an increasingly contentious topic since US President Donald Trump took office as he pledged during his campaign to build a wall separating the two countries.
