Reddit user UNBR34K4BL3 points out that you can open up an old ballpoint pen, cut out an empty section of the ink tube, and stuff that into the compressed air can to use as an alternatve. You probably won't get as much reach from this tip as you would from the original tube, but it should be sufficient to clean out the nooks and crannies of your keyboard or PC. Just be sure there's no leftover ink inside! As we've pointed out before, a a coffee stirrer also works for this.
