Ball hits lever, triggers linear motor which releases Bungee'd apparatus, which then starts the laser.

Laser starts robot. Robot triggers linear motor which redirects laser. laser now holds up plank. Robot pushes cylinder onto plank. Robot falls to the floor and throws a rock starting the scales. Scales are one of the two triggers for the rocket.

Meanwhile the steel ball falls into the car, drives forward spills out and goes through the trampolines. when it stops it hits a button causing the thruster at the top to stop and makes the block fall, cutting off the laser beam. this drops the plank and rolls the cylinder the laser was holding up into a button. This is the other rocket trigger.
