Real-life lightsaber

Pretty sure it's kind of like a controlled miniature flame thrower that works on butane, saw something like this a while back

And so why would it be green?? http://www.laserpointerpro.com/5in1-5000mw-532nm-beam-light-green-laser-pointer-pen-kit-black-p-1820.html?gclid=CjwKCAjwoNrMBRB4EiwA_ODYv4E-h2mhbK5ft76rOW3NVrc5TyfeFrTOJCHsNW5UHcjfVglELFivRRoCUx0QAvD_BwE "use it to light a cigarette or simply make a fire"

I'm colour blind, so I thought it was yellow like fire. Oops

There are green laser pointers that can pop balloons simply by touching them but those laser pointers are only custom made or used in labs
