Charlie hadn't moved. He hadn't even unwrapped the Golden Ticket from around the chocolate. He was standing very still, holding it tightly with both hands while the crowd pushed and shouted all around him. He felt quite dizzy. (11.20)
It's almost as if time has stood still. Charlie is totally unable to believe his own luck. And Dahl describes the moment so perfectly, it feels like we're standing right next to Charlie, jaws on the floor.

Everything that he had seen so far – the great chocolate river, the waterfall, the huge sucking pipes, the minty sugar meadows, the Oompa-Loompas, the beautiful pink boat, and most of all, Mr. Willy Wonka himself – had been so astonishing that he began to wonder whether there could possibly be any more astonishments left.

Charlie hasn't had a lot of astonishments in his life. He's been hungry and poor for quite a while. So imagine how spectacular it must feel to wander among minty sugar meadows and chocolate rivers. If anyone deserves such fun, it's Charlie.

Charlie Bucket stared around him in astonishment. This was the craziest elevator he had ever seen. There were buttons everywhere! (25.7)
The chocolate factory is astonishing right down to the last detail. Even the elevator.
