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!
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.
Laminar flow fountain designs are my current interest in creating kinetic art sculptures. I have a new display on the physics of fluid dynamics enhanced with fiber optics to create a science oriented art sculpture.
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.

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.
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!
The Nerdy Derby is a no-rules miniature car building and racing competition inspired by the Cub Scouts' Pinewood Derby. It is a creative teaching platform for kids to stay activity curious and get immediate tangible results.
