For the past couple of years or so, the National Building Museum puts on some big, really fun exhibit during the summer. Last year, it was a giant maze that was a blast to go through. This year, they built a giant ball pit called The Beach DC where everyone can pretend they are five years old again. On Wednesdays, it is open late, and at that time it is also a happy hour, a thing that DC does really well. The Beach DC is the best people watching. Watching men and women in business outfits play in a ball pit is quite frankly really entertaining. Watching adults create “ball storms” is also hilarious.
Also, I went in a couple of times, and I now want to study the physics of trying to move through a giant ball pit. There is serious friction and other forces trying to stop your movement. I seriously have started trying to consider the forces. The balls all have friction against each other and you.
Finally a 45 second slide show of still photos of people playing in the ball pit.
