Simple Light Tunnel

Project Number: 4

Parts Needed: Any Base Grid (Mini Base Grid Recommended), Battery Holder (B3), 2 2-Snap Wires, Light Tunnel (U30), Slide Switch (S1), and 1 5-Snap Wire.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the board first. Then, place parts marked with a 2. Install three (3) “AA” batteries (not included) into the battery holder (B3) if you have not done so already. Turn on the slide switch (S1). The light tunnel (U30) puts on a show. For best effects, dim the room lights. Try GENTLY pressing on the center of the mirror in the light tunnel, and notice how the light patterns bend inward a little.

Snappy: The light tunnel has 3 red, 3 green, and 3 blue LEDs. There is a mirror behind them, and a semi-transparent mirror above them; the combination of these produces the effects you see.
