This amusing arm-mounted vacuum is by Unnecessary Design Studio, a/k/a Matty Benedetto. It allows you to keep your fingers clean while picking up residue-laden snacks.

"The Snackuum™? The first handheld vacuum for picking up all your favorite snacks and delivering them directly to your mouth while keeping your hands pristinely clean. Our wrist mounted vacuum features a high suction hose just beyond your own finger. So now when you sit down with your snacks simply press the power button and dive into your dusty snack bag to firmly grip your chip without any human contact before your lips. No matter what the snack may be or where it's located, get a firm grip every time with the Snackuum."

For now, Benedetto isn't selling these. I think he's leaving money on the table--America surely has the market for this.
