anyone try this?

LED lights? Good grief! Smynx, when I was 17 and 18 I worked a boring job where I'd keep myself busy by assembling cables for technicians (RS232, null modem, IBM LAN, etc.) and after a while all the various parts presented challenges as to what other uses they might be good for. Hence, coaxial pipes. :) Of course, in an "emergency" (yeah, right) there was always your standard dented coke can with pinholes. ;)

yeah when you hit it, the bubbles would cause the lights to light up. It was so cool. Until my mom found it. lmao. that was great. she said "what f*** is this?" She thought we were cookin meth. HA HA HA HA

coke can with pinholes? wow, remember the days. How harsh that was...

Wow, you must've really made your mom worry. ;) And hey, poking pinholes in a coke can is a LOT easier than emptying and refilling a cigarette. ;)

No doubt. The coke can always worked in a pinch.

Go-go gadget.
