Aspen Hill, MD Indoor Activities

MoBu Kids' founder Melissa Steele devoted her time to entire classes of children for eight years before retiring to care for her two favorite youngsters—her son and daughter. Shortly after the birth of her son in 2005, Melissa opened MoBu Kids, an indoor playground and classroom for kids that was voted ParentsConnect Parents' Picks Best Kids' Party Place in 2010 and Best Indoor Playspace in 2009. During open play, youngsters scramble atop custom-designed foam playground equipment and roll around safe gymnastics flooring like Olympic-level tumbleweeds. They also test footholds in a rock-climbing wall and zoom down the slide of a petite tree house.

A more structured blend of learning and recreation characterizes small classes led by energetic instructors. Music and movement strengthens the link between notes and motion, bolstering language or motor and social skills according to age. Art-class masterpieces spring from the colorful depictions in a storybook, and ballet encourages dancers to forge creative steps, like the stubbed toe hop. Similar themes run through summer camps and private birthday parties.

Madame Tussauds Washington D.C. escorts guests on an interactive journey through American history. Only here, the past isn't manifested through movies, but through wax. Inside, The President's Gallery brings visitors face-to-face with all 44 US presidents, from Harry Truman to Abe Lincoln and his signature spinning bowtie. Cultural leaders, such as Martin Luther King Jr., stand tall nearby, and rock stars such as Bruce Springsteen and Bob Dylan compose silent jam sessions in the Vintage Music Room. Hollywood stars, sports heroes, and nonpresidential political figures round out the collection, which can be visited 365 days a year.

Ultrazone Laser Tag might be familiar to fans of The Real World, whose cast members—fed up with drama—blew off steam by ducking colorful laser beams in the sprawling multilevel arena's fog-filled maze. There's enough space for 45 vest-clad players to face off at one time, and plasma monitors let the next wave watch the game as they eagerly await their turn. The expansive recreation center also hosts sleepover parties that grant exclusive overnight use of the laser-tag facilities, the plasma-screen theater, and the room that's inexplicably full of doorknobs. Outside the arena, an arcade keeps synapses ablaze with video games, air hockey, and golf simulators, supplemented with slices of Papa John's pizza from the cafe.

Pilates is a low-impact, total-body discipline that focuses on the core to help keep the body balanced, toned, and energized. During the private equipment session at Fit to the Core Pilates, one of the studio's friendly and experienced instructors will teach you how to correctly use resistance machines, safely accommodating your skill level and fitness goals. Classes at Fit to the Core utilize STOTT PILATES equipment but also incorporate natural body resistance, stretching, and controlled breathing to build long, lean muscles while promoting physical and mental cohesion. Call ahead to schedule your one-on-one equipment session.

Adventurers explore the Roaring Twenties at a time when the museum's doors regularly would be shut tight. Museum-goers wander through an interactive series of exhibits that focus on Prohibition and the history of crime in general, and like apprehended bootleggers and serial jaywalkers, visitors can ink themselves with temporary prison tattoos and decide on a last meal, before springing themselves from the joint to analyze blood splatter like modern forensics experts. Interactive demonstrations in forensic science help museum-goers learn the stories that blood spatters tell before an exploration of prison tattoos shed light on the social orders in the pen.
