Zoom Tubes! As Seen on TV, and just as fun as it looks! It’s easy to connect the tubular track and use the wireless remote control to launch your racer up, around, over and back! There are infinite configurations, to keep your kids engaged and it promotes creativity, focus and experimentation. The Ultimate Bundle includes the 25-piece main kit with blue and orange RC racer cars, the 25-piece tubular expansion kit, and the crisscross crash connector! They light up, so it’s fun to watch them too! Build the track, light them up, but the fun is just beginning because the real treat is racing them! They have tubular traction technology which gives your racer 360-degree gription (is that a word?) velocity. Basically, they have grip + traction and it’s AWESOME!
