Safety first! Elise engineered a folding deck that acts as a safety gate when the gondola is in motion and acts as incline planes before and after the ride to allow the cars on and off!
These are the tracks that the gondola travels on. There are pulleys on each tower.
One of the challenges was to make a bascule bridge that pivots on a fulcrum.
The first challenge was to make strong deck suspended from a broom. Second challenge was to get rid of the broom and hold the deck up with anchors!
