You're looking for something that goes bad in less than 1.5-two hours. Say it takes 30 minutes to get to the hyperloop depot, 30 mins to Vegas, then 30 minutes from the Vegas hyperloop dept to get to the final destination casino or wherever its going.

And it needs to be something numerous enough that you could consistently fill a shipping container with it.
