Are satin pillowcases good for acne?

If you have acne-prone skin, fabrics such as satin, silk, and bamboo are better choices because they’re less absorbent and won’t draw oil away from your face.


Due to the Sun and Moon’s gravitational pull, we have tides.

This is because the Moon’s tidal force causes the Earth – and the water on it – to bulge out on the side closest to the Moon.

These bulges are what cause the world’s high tides.


 Chameleons change color to match their surroundings.

Yes, chameleons can change color by stretching and relaxing cells that contain crystals, which affects how the light is reflected. They can’t change to any color to match their surroundings, though, and their color changes don’t have much to do with camouflage.

Instead, chameleons use the crystals mainly for communication (dark colors signal aggression, like when a female doesn’t want to mate), but also temperature control (lighter colors reflect the heat). The dull brown and green “resting colors” of chameleons blend in with their surroundings until they switch it up, so they’re actually more camouflaged before they change color.
