Is a sham a pillowcase?

No. These “false front” pillow covers became known as pillow shams! A sham is a decorative pillow case that transforms normal sized pillow fills into useful accessories for one’s bedding set. Pillow shams come in three traditional sizes: Standard Sham (26″ x 20″), King Sham (36″ x 20″), and Euro Sham (26″ x 26″).

Fact

Footprints left on the Moon won’t disappear as there is no wind.

But wait a minute… if there’s no wind to blow them away then why is the flag blowing? Well, it actually wasn’t blowing.

That rippling you see is because of a stubborn telescopic horizontal rod that the astronauts were struggling to remove from the flag’s upper hem.
