Technically, it is my oldest child that has the touch, the chimp is just looking at it:
I didn’t actually notice right away what my child was doing, I was taking photos of another chimp at the time. Then I noticed that a crowd was gathering and that my child was talking to the chimp and showing the chimp pictures of itself and other animals. The chimp seemed pretty interested. This isn’t a great picture technically speaking, there was quite a bit of glare and the glass was really dirty right in that spot. Still, it was an interesting moment.
