Just in time for Halloween, something spooky and gadget related has popped up, the tesla radio in a jar. Posted on instructables.com user mrfixits, this non powered radio unit, dubbed “crystal radio circuit in a jam jar”, brings in all sorts of things, from soundwaves, radios, plaser pulses, and even thunder storms. Check out the spooky video of the radio in use.

The radio also plugs right into your computer’s audio jack so you can record, save, and share all of the spooky sounds you discover. This is an amazing tech creation that allows amateur scientists to record mystreious sounds on Earth and beyond.
