Walt Disney Imagineering built a real-life retractable lightsaber with a 3.28-foot plasma blade, and then Hacksmith decided to one up them by creating a strontium plasma lightsaber that burns at 4500°. Just on caveat: it does not have a 3.28-foot blade, although the strontium plasma blade is still powerful enough to roast marshmallows, duel with Darth Vader, and melting glass bottles.
This is a followup to their 4000° protosaber 2-years ago, which required you to wear a backpack to carry all of the hardware. Now, the strontium plasma lightsaber is 70% lightsaber, which means that you can wear the power pack like a belt instead. A custom manifold was required to fabricate the hilt, while the copper tubes it uses had to be cut and then soldered for the magic to happen. Lastly, two custom PCBs needed to be designed, which gives the lightsaber sound effects, auto ignition and valve control.
If you’ve never watched any Star Wars movie or read any of the franchise’s comics or books, the lightsaber is essentially a luminescent plasma blade that typically measures around 3-feet in length emitted from a metal hilt. There has been at least one lightsaber battle in each installment of the Skywalker saga films. Rotoscoping was used to create its appearance in the original films, and digital effects later used for the prequels as well as sequel trilogies.
