The Mask Launcher; Like An Airbag For Your Face

0

One of the most effective ways to slow the spread of pathogens like the novel coronavirus is to have individuals wear facemasks that cover the nose and mouth. They’re cheap, and highly effective at trapping potentially infectious aerosols that spread disease. Unfortunately, wearing masks has become a contentious issue, with many choosing to go without. [Allen Pan] was frustrated by this, and set out to make a launcher to quite literally shoot masks directly onto faces.

To fire the masks, Allan built a pneumatic system that gets its power from a compact CO2 canister. This is hooked up to a solenoid, which is fired by the trigger. The high-pressure CO2 then goes through a split to four separate barrels cleverly made out of brake line ([Allen] says it’s faster to get parts from the automotive supply than the home store these days). Each barrel fires a bola weight attached to one of the strings of the mask, in much the same way a net launcher works. The mask is then flung towards the face of the target, and the weights wrap around the back of the neck, tangling and ideally sticking together thanks to neodymium magnets.

Amazingly, the mask worked first time, wrapping effectively around a dummy head and covering the nose and mouth. Follow-up shots were less successful, however, but that didn’t deter [Allen] from trying the device on himself at point-blank range. Despite the risk to teeth and flesh, the launcher again fires a successful shot.

While it’s obviously never meant to be used in the real world, the mask launcher was a fun way to experiment with pneumatics and a funny way to start the conversation about effective public health measures. We’ve featured similar projects before, too. Video after the break.
