copy a database within SQL Server Express?

I would like to make a copy of a database I have but keep it on the same server as a test database. However, everything I have found is to use the copy database wizard (I am using MS SQL Server Express).

The instructions always say: In SQL Server Management Studio, in Object Explorer, expand Databases, right-click a database, point to Tasks, and then click Copy Database.

I don't have the Copy Database option. I am running as an admin, so no clue why it is missing for me - is it something I have to install separately? I can't do the Detach/Attach since it is copying to the same server. I tried detaching, copying the MDF/LDF, renaming, attaching but as you can imagine that messed a ton up :) I am not great with SQL to do it all programatically. Is there a tool out there I could use?
