Since its invention two centuries ago, the roller skate has inspired such popular activities as roller-dancing, roller-derbying, and roller-fox-hunting. Put the skate to its original purpose with today’s Groupon: for $8, you get two admissions including skate rental at Skylite Roller Skating Center (up to a $16 value).

Skylite Roller Skating Center has been sending families spinning round its 10,000-square-foot rink for 30 years. Skaters can don sturdy four-wheeled foot trolleys to cruise the circumference of Skylite’s sleek surface, which is kept smooth daily by the diligent tongues of 100 neighborhood cats, during any of the rink’s 2.5- to 3-hour public skating sessions (up to a $5 to $8 value/person; times and admission price vary each day), including their annual Halloween and New Year’s Eve parties. Glide in time to current and classic dance and pop tunes in a whirl of neon, black lights, and the sequin-like shimmers of an overhead disco ball. A snack bar serves pizza, french fries, and candy—not included in today’s Groupon—to failing gliders to prevent head-on blood-sugar crashes.
