I think I'll post more than one as they come to mind. The first one is a little weird for some maybe haha and definitely not appropriate if you're claustrophobic or afraid of heights.

So here it goes:

Get some drinks and some sweets, get into an glass wall elevator that is in a tall building and by the side of it to have a great view, and go to the top floor.
Now the secret would be that right before the elevator gets to the top floor, push the stop button and lock it there.

That's it, enjoy the view, from the elevator at the top of the skyscraper :)

I hope you like it.
