Inspired by our local playground that recently renovated and has to put up [warning signs saying that the metal slides get hot in the sun](https://sanjosespotlight.com/heat-scorches-east-san-jose-emma-prusch-farm-park-playground-slides-equipment/), but I’ve seen this same issue at playgrounds with plastic pieces. The day will be reasonably warm but we still can’t go to the playground because it’s just too hot to climb on.

Name something that doesn’t get hot in the sun.
No such material exists. Everything absorbs heat. And will be hot to the touch.
The only solution is to shade the object with a sunshade.
Even if you made it out of mirrors the glass would still be hot.
