When kids are small, the whole world seems big: dad's hands, tall buildings, even the family dog. Maybe that's why superheroes are such a draw to them. They're these characters that are as big in proportion to the world as the world is in proportion to kids, and there's no kick to the imagination quite like being able to leap tall buildings in a single bound. At the Superhero Showdown, taking place on Wednesday, June 27, at JUMP, kids can don superhero costumes they've designed and made themselves, cut slogan videos, color in superhero comic books and choreograph a superpowered fight scene for a short action film. After lunch, the 10- to 14-year-old heroes can explore JUMP's unusual spaces like the Nest and Deep Tinker, and check out the slide.
