If you want to keep a kid busy for hours, you can hardly do better then a LEGO set. Two new lines out from our favorite bricklayers take the building occupation on the road. 
The LEGO Racers' Tiny Turbo Fold-Out Race Tracks give a whole new meaning to backseat driver. The plastic case that carries their bricks on the road doubles as a race track when opened up. Each set lets them build two different cars while they're riding along in the back of the car, and than it's all about the racing action. So keep your hands on the wheel while they do the steering. Get the Ice Rally (for kids who drive to extremes), Thunder Raceway (above), or take on a Desert Challenge, all straight from LEGO for $14.99.

LEGO Creator Minis pack three times the fun in a plastic container that's three times smaller than your average LEGO product box - leaving more room in the suitcase for extra swimsuits. There's more room in your wallet too; the new toys are a steal at $4.99. Get the Mini Jet or the Mini Off-Roader from LEGO.
