## Description

Yay, a plastic tube! No, Adafruit jest. This is no ordinary plastic tube, but rather a side-lighting fiber optic tube.

This is a pretty neat way to glow up. Light in the fiber optic cable zooms through the core by constantly bouncing off of the edge of the molded plastic, a principle called "total internal reflection" (which also kinda sounds like a very expensive meditation island retreat). When the light pipe doesn't have total reflection, you can get a nifty lighting effect from the light illuminating the plastic tubing.

This tube is 5mm diameter, but is nice and flexible plastic and when lit with a powerful LED, has a nice glowing effect. You can cut it down from 1 meter with diagonal cutters.

**Note:** This is *just* the tube, and does not include an emitter LED. [You'll also want to grab one of Adafruit's fiber lights. Adafruit have got them in red, green, blue, white, and Adafruit pink!](https://core-electronics.com.au/search/?q=fiber%20optic%20light)
