Round and round
Why do we feel dizzy when we spin?
Srishti Rawat , Kanpur
View AnswerOur ears play a major role in making us feel dizzy when we spin. The inner parts of your ears give you your sense of balance. These inner parts have hollow spaces filled with a liquid, and the walls of these hollow spaces are lined with tiny hair cells. When you move around, this liquid sloshes around and bends the tiny hair cells, which are connected to nerve cells that send messages to your brain, giving you your sense of balance. So when you spin, the liquid in the inner ear spins as well. When you stop spinning the liquid keeps moving for a bit, confusing your brain into thinking that you're still spinning even when you're standing still, which makes you feel dizzy.

Turning green
Why do copper vessels turn green with time?
Syeda Sara Yaseen , Hyderabad
View AnswerJust like how iron rusts, copper undergoes chemical reactions when it is exposed to air. This results in the formation of a pale green outer layer called a patina. Did you know that the Statue of Liberty is made of copper? It was originally a dull brown colour. Over time, Lady Liberty turned to the green colour we see today due to oxidation!

Do plants grow well if we talk to them?
Subhashini U , Bengaluru
View AnswerDespite speculation on the subject, there’s not much conclusive research on whether plants respond to human conversation. However, some scientists and researchers have found evidence that plants react to a number of environmental stimuli, including vibrations. Since sound is essentially a form of vibration, it is possible that speech and sound could have an effect on plant growth.

Funny matter
Where is my funny bone?
Hiranmoy Das , Mumbai
View AnswerHave you ever hit your elbow joint in a particular spot and felt a tingling or prickly kind of dull pain? That's your funny bone. It doesn't really hurt as much as it feels weird. The ‘funny bone’ got its nickname because of that funny feeling you get after you hit it. But did you know that it isn't actually a bone? Running down the inside part of your elbow is a nerve called the ulnar nerve. You get that funny feeling when the ulnar nerve is bumped against the humerus, the long bone that starts at your elbow and goes up to your shoulder.
