Ruby Laser

Exhibit

This custom ruby laser was built from surplus parts, and produces enough energy in a single shot to drill holes in metal. Ruby lasers have also been used to make hologram snapshots and to measure the distance to the moon.





HomeBrew Robotics Club

Exhibit

''HomeBrew Robotics Club'' members have a wide range of expertise in robotics from beginning to expert and there are no age restrictions, so if you have an interest in the field of robotics, please join us.


Rory Dawson

Performer

Rory has been playing freestyle footbag and developing robotic systems since 2004. Eventually he discovered that he could combine both passions by lighting up and roboticizing footbags and shoes with LEDs and sensors.


Let’s measure the Speed of Light!

Presenter

Everyone talks about the speed of light, but hardly anyone every measures it
This is a fun backyard project - we'll use a laser-pointer (the kind you use to annoy cats); a signal generator will switch the beam on and off a million times a second. A piece of glass will split the light into two beams - one goes to a nearby photodiode, the other laser beam bounces off a distant mirror and returns to a second photodiode
Watch the outputs of the two photodiodes on a dual-trace oscilloscope - you can see the difference in arrival times of the two beams. Divide the distance and by the time difference -- and there's the speed o light!



Prism gyroscope

Exhibit

The prism gyroscope combines optics and mechanical motion on a large scale.rnrnThe prisms refract light and move to change the amount of refraction.rnThe gyroscope can be spun manually to observe the rotating refraction.




Singing Laserium

Exhibit

The Singing Laserium is a mechanical visualization of song. You sing into either (or both for a duet) of the cans to modulate the path of the laser beam. Watch the patterns you create on the wall behind the display.




Amazing Science

Presenter

Giant 18 inch diameter smoke rings traveling 30 feet or more, bubbling liquids changing colors, and spheres that seem to float in mid air are just a few of the amazing science spectacles that will fascinate all ages. Build your own to entertain small groups of friends or audiences at a science fair. Spectators will gain insight into how to build the apparatus.



NASA Centennial Challenges

Exhibit

Centennial Challenges is NASA's multi-million-dollar prize competition program that engages citizen inventors, academia and small businesses to solve problems that benefit NASA and the nation. Program Manager Sam Ortega will be speaking in a panel discussion — NASA: Challenging America To Invent — and the program will have an exhibit space throughout the event.


Life-Size Mousetrap

Exhibit

The Life Size Mousetrap is a fantastically hand crafted, 16 piece, 50,000-lb. interactive kinetic sculpture set atop a 6,500-square-foot game board. This giant Rube Goldberg style contraption comes complete with a Vaudevillian style show, original Musical score by the one woman band Esmerelda Strange, Sexy Mice can-can dancers, clown workers, acrobatic hi jinks, and other spectacular scenes dedicated to the pursuit of spectacle-laden fun!
