Move the matchstick Tricks ABC Science

cheap moncler coats 2. Cover your creation with an upturned monlcer down jackets glass or plastic cup. Now challenge a friend to move the matchstick 90 degrees without lifting the cup or knocking the 20 cent coin over. Make sure to ensure them that this is, like, totally possible. cheap moncler coats

cheap moncler jackets sale 3. When you’ve had enough of your friend begging you to show them how it’s done, do this: rub a plastic pen (or fork or comb) in your hair. cheap moncler jackets sale

cheap moncler outlet 5. You’ll easily rotate the matchstick 90 degrees cheap moncler coats but go further and, nine times out of ten, it falls off the coin. If you’re extra lucky, you might turn it a full 180 degrees. Either way, it’s spooky and amazing! cheap moncler outlet

moncler jacket sale What’s going on? moncler jacket sale

cheap moncler jackets Some combinations of certain materials, such as plastic and human hair, can become electrically charged when moncler mens jackets rubbed together. It’s called the ‘triboelectric effect’. ‘Tribo’ is Greek for ‘rubbing’ and electric comes from ‘electrum’, which is the Greek word amber. cheap moncler jackets

moncler factory outlet Amber is the fossilised resin of trees, which also attracts lightweight objects when rubbed with fur. The Greek philosopher, Thales of Miletus (c620 c546 BCE), first noticed this property of amber over two and a half thousand years ago. Today, moncler Moncler Outlet outlet millions of school kids independently rediscover the same phenomenon whenever they touch a metal door handle after scuffling across carpet. moncler factory outlet

moncler outlet jackets A physicist called William Gilbert (1544 1603) coined the English word ‘electricity’, by which he meant “like amber in its attractive properties”. But neither Thales nor Gilbert ever figured out what was really going on. Today, thanks to a cavalcade of scientists who followed in their footsteps, we know it’s because one of the materials gains some extra electrons, which it ‘steals’ from moncler sale the other. That doesn’t make it any less spooky though, because nobody can, nor ever will, see this happen with their own two eyes. moncler outlet jackets

moncler outlet sale Electrons are way too tiny to see but we know they repel each other. We cheap moncler sale also know that protons attract other protons, but repel each other. Together with neutrons, theses three, tiny, invisible particles combine to make every atom, and therefore every material thing you will ever encounter (including yourself). moncler outlet sale

moncler sale Every neutral atom has an equal number of protons and electrons. Losing an electron makes atoms positively charged, while gaining one makes them negative. Rubbing a plastic pen (or comb or fork) through your hair endows the pen with extra electrons, which it appropriates from your https://www.moncler-jacket-outlet.com noggin. Those extra electrons will now repel the electrons in any other object and attract moncler outlet sale its protons but here’s where cheap moncler it gets tricky. That fork or comb will attract just about anything that is light enough, even if that thing has not been rubbed by anything else. moncler sale

moncler sale outlet That’s because the electrons in an atom buzz around their beloved protons in tiny spherical orbits. Bring a charged pen buy moncler jackets (or comb or fork) near such an atom and you’ll repel its electrons, which distorts their tiny orbits. The electrons now effectively spend a fraction more time on the far side of these orbits. That means the protons cheap moncler outlet in the atom are now, on average, a little closer to your charged pen moncler sale outlet than its electrons. Being nearer makes the moncler outlet online force of the proton’s attraction slightly greater than the force of the orbiting electron’s repulsion cheap moncler jackets and, phoomba! The whole atom is attracted to your pen. moncler sale outlet

moncler outlet But, like I said, nobody will ever actually see the distortion of an electron’s orbit or anything else they get up to. And that’s why, two and a half thousand years after Thales played with amber, we are still mesmerised by a matchstick magically following a charged up pen moncler outlet.
