Subject: how to create Class object with name determined at runtime

I hope someone can help with this - I am a Ruby newbie.

In my code I want to decide at runtime which type of object to create, 
based on a variable holding the name of the class.

So I have classes Foo and Bar and a string todays_class.

If todays_class = "Foo"  I want to say my_obj = Foo.new
if todayS_class = "Bar" then my_obj = Bar.new

Except I've got a lot more than two classes and I'd prefer not to use an 
if or case statement, so that I don't need to change the code if I add 
another one to the list.

Any suggestions on a neat way to do this?

Thanks
