Would you tell me if it is correct and natural to say just for educational purposes when you are asking for informaion that you need just to broaden your undestanding of things? For example:
I understand that I don't have to know how that appliance works, but just for educational purposes can you explain it to me.
I've never heard anyone say it, but it's the only phrase I've been able to come up with to convey the message. Is it natural? Either way can you please give me alternatives?
