A company called Han Pham has developed a simple syringe disposal system that reuses a standard 12-ounce aluminum can. The device ensures safe disposal of needles to avoid infecting anyone with tainted blood. It simple, low-tech approach involves covering the top of a can with a bright yellow, one-way lid. A lot safer than dropping used syringes on the sidewalk, or even throwing the pointy guys in the trash, don't you think? So crack open a Bud, and get your vaccine on.
