A short talk that tells the story of all the random things that lead to the invention of the little toy Strawbees. What do monsters, clothespins and kids in India have to do with the invention of a new construction toy?
Glowing beads dance to a different "beat" as they levitate and move under only the influence of sound waves within this unique spin on the classic Kundt's Tube. Change their dance using the Arduino based controller.
Stringmaking Demonstration The knowledge of how to ply fibers into usable lengths is one of the most basic, essential and important of human life skills, and yet, most modern people have never seen it done. Cordage (string) & rope have long been utilized (and treasured) by humans from every part of the world as tools in fishing and hunting, for carrying burdens, constructing shelters, in textiles, for tying bundles of possessions together, and so on. This demonstration helps bring this essential technology to life.

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.
