In this project, two spoons are wired to either end of a circuit - one to power, the other to ground. It is inspired by the use of spoons as a musical instrument by striking them together in a rhythmic fashion; both spoons are conductive so that, when struck together, they close the circuit and thus cause an LED to light up. In this way, it adds a flashing light show to accompany the clacking of the spoons themselves.
The lower half of the spoons' handles are tied with ribbons to insulate the grip and make sure the LED only lights when the convex sides are tapped (the main musical part, not just random contact on the back end.) The light green ribbons also add a little homemade sparkle to a homemade instrument. The ribbons are taped down with basic Scotch tape, and the spoons are clipped close to the inside of the alligator clips so nothing comes loose with the kinetic force of playing the spoons.
V=I*R, so R=V/I = (5-2)/.02 = 150 ohms
