In a fluorescent show of unity across the border, a set of bright pink seesaws were installed between the United States and Mexico with children bopping up and down along the divide.

Designed by University of California Berkeley architecture professor Ronald Rael and San Jose State design professor Virginia San Fratello, the installation popped up over the weekend at Sunland Park, New Mexico, near El Paso and Ciudad Juárez.

Photos and videos showed children and adults on both sides of the border playing on the seesaws Sunday.

"The wall became a literal fulcrum for U.S.–Mexico relations and children and adults were connected in meaningful ways on both sides with the recognition that the actions that take place on one side have a direct consequence on the other side," Rael said in a statement.

The idea for the teeter-totters was first conceptualized 10 years ago as part of Rael's book "Borderwall as Architecture: A Manifesto for the U.S.-Mexico Boundary."
