That quite literally was a fingerprint because it left the surface layers of skin from your finger. The reason ice is sticky is for that very reason. Ice itself is so cold if you touch it with skin because your body secretes tiny amounts of liquid, sweat, which is a salty fluid onto your skin surface it actually makes your skin stickier. This is why we have it. It’s for grip. If you then touch that onto a very cold ice surface the ice then re-freezes the liquid on your finger. Because that liquid is a fluid and it has got into all the nooks and crannies on your finger it then freezes solid and will form a very tight bond between your finger and the frozen surface, the ice. You get stuck to the surface. If it’s an ice cube – if it’s okay because there’s enough heat flowing through your fingers (usually to re-melt that transient freezing)
