My kids were asking me what is inside a golf ball tonight. So I took an old Titleist Professional 90 and cut it open.
We found the world’s longest rubber band inside. The ball started crackling like rice crispies and expanding. It then kind of exploded as it unwound, exposing the core. My kids thought I was pretty cool for showing them this.
My kids now refer to a wound ball as “old fashioned.” Their education continues.
