What Happens if You Open a Decade-Old Can of Play-Doh
There’s something that’s just so fun about Play-Doh, which has made it such a popular game among kids for years. But what happens if you forget about it for 10 years and then open the container? Well, after a decade, your Play-Doh might just grow some crystals! As you can see in the picture below, this is how one person’s old Play-Doh looked 10 years later.
There’s actually a very simple reason why Play-Doh grows crystals with time. It has a very high salt content! So as the Play-Doh dries out, salt crystals form. While it may take you by surprise to see clay growing crystals, it’s a totally normal reaction–so there’s no need to freak out.
