I need advice about making a club interesting!

I have recently been helping my friend keep a World Community club going.

We have had presentations from people from many different countries, describing the culture there, play games, learn some different sayings in different languages, we had a potluck, and sometimes we would bring in food!

But, not many people come!! It has only had a max of 7 people coming… :/ And Im running out of ideas to make these meetings more interesting, and fun!! Because I sure think that this club can be made a lot more interesting to high school students, but I cant think of anything else!!
