Not even a little sarcasm.Unless you have a need to buy a DVM for future use I would go with the potato. Simple and inexpensive.
I cannot recommend this but I am told it works. Proceed at your own risk. Touch both leads to your tongue at the same time. The negative terminal will hurt more. The difference is noticeable.

This is a valid method yet difficult to see for obvious reasons.Hook to a 12v light bulb. If it lights you have it right. If backwards the room will get dark due to sucking the light back in.
