Well, if you were going to do an experiment without a question (or a well-defined one), you would just be doing one to 'see what happens.' Well, one of two things will occur: Something will happen, or nothing will happen. In either of these cases, if you don't have an original question of why you are doing the experiment, you don't know what you're looking for. Nothing may happen, but how will you know if you weren't really looking for anything to happen. Something may happen, and you may not notice it as you weren't sure what you were looking for. Also, something may happen and you may notice it, but you won't know why it did what it did, or have a theory as to how it could have happened because you didn't try to see if anything specific happened in the first place.
If you're test isn't controlled - or doesn't have a question or hypothesis - then it is basically just an accident. Whatever happens happens, but you aren't doing anything to make anything specific happen.
I don't know what an Odyssey Writer is, but I hope this helps!
