While Pixy Stix may have gotten you all hopped up as a child, you’ll need something a bit stronger in your adult years. Enter Nixie Tubes — basically grown-up Pixy Stix laced with 100mg of caffeine.

ThinkGeek has the exclusive on Caffeinated Nixie Tubes. Five tubes nets $9 plus shipping and each tube contains about 20% more caffeine than a standard cup of coffee. So if you don’t like the taste of coffee and your insides have been rotted by carbonated beverages, looks like powder form might be the next best way to get your fix.
