I'm weird. I know.
It occurred to me last night that the Universe of Energy does not have a shop at the exit like most other pavilions do. I wonder why this is? Is energy related merchandise not popular? Does Exxon have so much money they don't care about merchandising?
I think they have the room for it in the exit area.
Personally, I think they could sell a lot of stuff. Besides the standard t-shirts and tchatchkes, they can sell solar powered toys and inventive things like that.
