Motion sickness is also known as travel sickness, sea sickness or air sickness. It can happen in a number of situations, not all of which involve movement, and is a very unpleasant sensation. As part of our Have You Ever Wondered series, our Science Editor Sam finds out what causes motion sickness, and if there is anything you can do to prevent it.
What on earth is a Schnitzeljagd?’ I hear you say.
A Schnitzel is a German word for a thinly sliced piece of pork, chicken or veal, which is dipped in egg and then coated with breadcrumbs. Similar to chicken nuggets but much tastier! Jagd means hunt.
A Schnitzeljagd means a chicken-nugget-hunt? Not quite! The word Schnitzel is also used in Papierschnitzel – little bits of paper.

Alan Bean, the fourth man to walk on the moon, said in 1969
“The only thing you can see from the moon is a beautiful sphere, mostly white, some blue and patches of yellow, and every once in a while some green vegetation. No man-made object is visible at this scale.”
But if you can’t see the Wall from the moon, how about somewhere closer to Earth? The International Space Station (ISS) maintains a low earth orbit of between 330-435 km above our planet’s surface.
