While Christmas may have just passed, there’s just enough time left in winter to justify wearing your ugly Christmas sweaters for a few more days. If you’re not one of the lucky ones with an old sweater from Grandma, you can still turn your least favorite sweater into the most epic flame-throwing Christmas sweater there ever was.
[JAIRUS OF ALL], maker of explosive and other dangerous ideas, came up with a DIY ugly Christmas sweater that shoots flames on command. In order to produce the flame-throwing effect, he uses piping from a fish tank airline hose with a T connector attached to one end and epoxied to the middle of the sweater. The piping runs down the sweater to a can of butane fuel that he can control from the nozzle. Once the fuel is being released, he uses a lighter to initiate the flames from the sweater.
The flames are quite impressive, so definitely use caution if you intend to replicate this build in any way. It would be helpful to have a friend with a CO2 fire extinguisher nearby as well.
For a less life-threatening build, fellow builder [Price] created a Christmas tree-themed sweater lined with LEDs and USB-powered figurines, connected to a power supply in his pocket.
