Guitars
One of the sculptures hanging in the Washington Convention Center.
Satellite
Hanging above the Lockheed Martin area of the hall.
Robot Guy
One of many constructed from Lego pieces.
Fighter
Not an especially unusual sight considering the heavy presence of the US military at this show.
Black Helicopter
One of those hovering overhead and very stealthily watching you. :-)
Coast Guard
Isolated at the end of the main hall in the Homeland Security area.
Robot Wizard
Squids 4 Kids
That's the name of the group, associated with Stanford University, sponsoring this hands-on experience.
Bar
One large booth offering refreshments (non-alcoholic) for it's visitors.
Sphero Table
Everyone gets a chance to control their device, although finding yours could be a problem. Love the kid in the chef's hat at the right.
Coding Table
I couldn't see exactly what they were doing on the tablets but the table was always jammed.
Super VR
Driving Lessons
The army was teaching kids how to control their robots. Never too young to recruit, I guess.
Diner Stools
Smoke Rings
Fill the bucket with smoke, cover one end with a cloth, and let an enthusiastic kid hit it to produce the rings.
Science Experiment
Space X
Since most of us can't afford to take one of their trips to space, a green screen is the next best thing.
Space Camp Gyro
I wish they were letting adults take this for a spin.
Flipping a Lid
Put some pie tins on top of a Van de Graaf generator and turn it on.
Aisles
The main hall of the science festival was a long hike.
Flight Simulator
I usually crash.
Playing
A cadet from the Naval Academy shows a youngster how the Ozobot follows the line.
Missile Command
Not sure why the Department of Energy would offer this game in their booth, other than that they manage our nuclear weapons.
Lego Bridge
Fill out some kind of prize form, put it on the Virginia side, and the conveyer belt transports it to the box on the Maryland side. Simple.
Skulls
I think they were explaining evolution?
