Is There a Scratch and Sniff for Hardness?

I remember always liking being the first person to like, get stuff. There was a thing at my school where you put your hand over your mouth and got one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen girlfriends. I didn't even know that was a thing that you wanted. And when I finally got it, I was like, oh my God, I haven't ever done it. Oh my God. So I was owning up to it. It's not a scratch and sniff for hardness. Well, what's the equivalent? Honestly box, by the way. That's hard as nails.
