Anyone who has longed to be a kid again, take note. A London gallery has turned its space into a giant ball pool in aid of charity, the Independent reports. The interactive installation, which promotes the transformative power of play, contains 81,000 white plastic balls and has a maximum capacity of 30 people.

The project was developed as a collaboration between creative agency Pearlfisher and the Right To Play charity. Pearlfisher has pledged to give £1 ($1.50) to the charity for every individual that jumps into the pit.

In an interview, Pearlfisher’s Chloe Charlwood told artnet News: “It was an idea that we had towards the end of last year that was inspired by the idea of snow, christmas and winter scenes. Snow is obviously renowned for encouraging play in all of us.” “Our normal lives are often dictated by the pressures of normal life,” she continued. “Children are completely uninhibited when they’re playing and there’s been lots of studies that have shown that play can bring about extraordinary results in creative thinking.”

Charlwood said that the agency’s gallery, which usually functions as its showcase space, has been “inundated” by visitors. “We’ve been absolutely overwhelmed by people who have wanted to come, people who have come, who have absolutely loved it.”

In a statement, founding partner and CEO of Pearlfisher, Karen Welman said, “Our London studio is a former school and an ideal venue for this art installation to come to life. Fundamentally, “JUMP IN!” is about celebrating creativity and positive human connections through the power of joyful play.”

According to their website, Right To Play is a charity that “transforms the lives of over one million disadvantaged children every week across Latin America, Africa, the Middle East and Asia through the power of sport and play.”

“Jump In!” is at Pearlfisher Gallery until February 13.
