On July 28, 2019, three pink teeter-totters were erected on the border wall between Ciudad Juárez, Mexico, and El Paso. Texas. For 45 minutes these teeter-totters brought children and adults together to a wall that was constructed to keep them apart. Sube y Baja is a fictional story inspired by these events—two children, David and Citlali, from opposite sides of the fence come together for a brief moment.
