Remember Pixie Stix or even Raven’s Revenge (popular powdered candy in the 90’s)? Well, Nixie Tubes from ThinkGeek is more of the same, but better. They “are sweet, they are sour, and each tube is loaded with 100mg of caffeine (more than most energy drinks).”

A pack of five tubes is going to run you around $9, which is a bit pricey for candy. If you�re in a pinch and need a quick (and tasty) pick-me-up, then one of these might just do the trick.
