Once you get it right all five carts should be able to bounce off your tower ceiling and into the exit.

Like I said, this will take some tweaking to get just right. This is the first hard level to optimize getting the precise bounces for a convoy is quite tough. Then build upwards with triangle arches, leading to a single solid platform in the carts' flight path, just below the laser. Inner ramp instead of using a bridge, I’ll use this trick quite a bit, saves a lot of money. Begin with a hexagon shaped construction to give your tower a strong base. You need to make a tower with a single solid platform at the top that the carts can deflect off of while maintaining their momentum so they can still reach the exit. The carts will pass through the portal, onto some orange gel, then bounce off of the blue gel and into the laser above. The carts will be landing on your "V" bridge hard, so support it from above and below with triangle arches. This will also make their passage into the portal consistent which will be important as they move into the final part of the level.
PORTAL BRIDGE CONSTRUCTOR BRIDGE CONSTRUCTOR HOW TO
Figuring out how to use a companion cube as a shield to block the laser attacks from a turret took enough clever. Because the carts likely won't be landing on their wheels, its good to have a "V" shaped bridge that they can roll on to get back on track. Bridge Constructor Portal is at its best when it focuses on one or two key ideas. Using the anchor points below the portal, build a shallow landing pad that the carts can safely land on. Support it from below so it can handle multiple carts, then send the cart through to make sure it lands on the blue gel and flies toward the right side. To begin, build a simple ramp in front of the cart spawner. This level's constructions are deceptively simple, and will probably require a lot of tweaking to get just right.
