Glow-in-the-dark shoelaces are special laces that can light up in the dark. Imagine regular shoelaces, but these have a cool twist – they absorb light during the day and then glow in the dark when it’s nighttime. The secret is a material called phosphorescence, which stores light energy and releases it later. So, when you’re in a dark place, like walking around at night, these laces emit a soft and visible glow, making your shoes stand out and look pretty cool.
