PSA: KidsAreStupid, sunscreen destroys plastics, but they will spray it on Legos to "make them shiny"
My daughter did this to an $80 set. At least a dozen cracked or broken pieces, and it happened fast. I could still smell the sunscreen heavy in the air as she was crying about cracked pieces.
We used it as a teachable moment about only using things for their intended purposes. but still alot of tears.
