The old-school playground equipment defied gravity and physics, making early 20th-century play areas dangerous. Grandpa may have claimed he walked uphill in the snow to school every day, but these vintage devices were truly perilous.

Barrel-of-Fun

In 1922, Hill Standard’s Barrel-of-Fun was likened to a mechanical greased pig. Anchored in concrete, this 140-pound steel barrel challenged kids to either dive over it or hug its smooth surface and spin. Some even tried logrolling on top, but falls were common and landings were anything but soft. While balance barrels still exist today, they’re typically safer, with soft wood chip beds, lower heights, and handles to prevent falls.
