What is the best way to show a short list of terms in varying size in a mobile device

A client of mine wishes to display a list of "hot" words (in different length) on a mobile device. The problem is that they want to display them all, in full length, and that they won't use a lot of horizontal space.

Are there some good suggestions on how to solve it?

As you can see in the attached image, I thought of showing a select box or a "word carousel":

Are there any more solutions to this problem?
