Step 1First something or someone presses the pad which then leans the car forward and then makes it roll down the track.

Step 2Now the car will hit the first block and tip it over hitting the next block and the next block with a thumb tack on it.

Step 3After the last block with the thumb tack falls it will hit a balloon which is holding a propeller.

Step 4

After the balloon is popped, the propeller will begin to spin raising the flag. GO VOLS!

Step 5As the propeller spins, it releases a marble which lands on a balanced catapult then launches a small Lego man into the air.
