Batteries dont typically have exposed copper, but if thats the route you want to go just buy some 1/2 inch copper rod off ebay, its like $12 for 6 inches. Super soft metal, you can work it by hand with a hacksaw and file/sander.

I wonder if your child can taste that subtle electric effect from the battery (ever lick a 9v?)

I definitely did that “touch the tip of the battery thing” as a kid. There was a “pleasant” metallic taste to it. If that’s what’s attracting your kid you may have to recreate that.
