While you might think of slot-car racing as something for kids, I personally think it's something you never grow out of. As you grow up and get bigger, you just need your slot-car track to grow up and get bigger with you, right? Right!

Just take a gander at this 8-Lane Salextric slot-car track. The thing is a monster. It's made with great quality, preventing power-supply faults and car-derailing bumps, letting you race without distraction or mishaps. Just clear out the basement, invite over a bunch of your friends, and have the weekend you didn't realize you wanted to have. You can't resist it, I know.
