Hot Wheels© Track Builder Construction Crash Kit-Combine Hot Wheels© Track Builder and bricks for epic Hot Wheels© action! There are 4+ unique builds with 4+ different pay offs with the Track Builder Blast It Kit. Take the checkered flag or send brick builds flying, launching cars and causing total destruction. Launch your cars on tracks and configure sets with brick components to foster creativity and experimentation! Re-configure and customize with bricks and Track Pivot Points for nearly endless configurations and crashing action. Blast through two crash panels before you hit the Blast Block and trigger the winning flag with the Blast Race Tower hero build! Hit the blast block to send the bricks flying with the Loop Crash! With the Gauntlet Crash build you hit the blast block to launch a second car. The Tower Takedown Crash has a ramp on the outside of the tower to launch mid-air to try to make it over the last Trick Brick and down the tunnel to the Blast Block. Hit the Blast Block for ultimate destruction when the tower goes down! Many of the items in this kit have more than one use, so kids can keep their imaginations-and their tracks-growing with a series of nearly endless configurations. Includes blocks in the box and 1 brick-compatible die-cast car. Not for use with some Hot Wheels© vehicles.
