Vacuum Straw Thingy

I kept seeing commercials for those vacuum things or attachments that could suck dust up from the bottom of a cup full of screws or something without sucking up the screws. I thought about buying one, but really, it's just a vacuum attachment with some straws in it. So I made this attachment (it fits the hose on both my dyson upright and my handheld eureka vacuum, should fit any hose that is 32mm od) and shoved some stirrer straws that I had bought at the supermarket into one end. I made sure to put enough straws so that they were friction fit inside, but none of the straws were crushed. It seems to work fairly well, though in use, I realized how LITTLE I actually needed this. But maybe you do.
