The Paul Walker Foundation was started by the late-actor's daughter, Meadow Walker, after his death in 2013. The charity helps promote ocean and marine-related causes. In addition, the charity provides marine-relate youth programs and scholarships to students studying marine sciences. Walker studied marine biology in college and spent much of his free time in the ocean.
Omaze works a bit like a raffle, with a name drawn for the top prize. People can spend money to purchase more entries. Perks, like a t-shirt or a signed movie poster, are given to those that buy a certain amount of entries. In this case, all of the prizes are Fast & Furious themed.
Fans of the franchise have nine days to donate and enter. The winner will be flown to Atlanta, put up in a hotel, and taken to the set of the latest film. They'll also get to meet both the film's cars and the stars. We know the production has started on the film and that there have been a few surprise additions to the cast. Omaze doesn't say when the set visit will take place, but the winner should expect the visit to take place soon.
