Why do we get Hiccups?

Everybody gets hiccups (also sometimes spelt ‘hiccoughs’). Even when babies are still in the womb they hiccup, which can feel very odd to their mother! But why do we get them and how can you stop them?

What are Hiccups?

Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat. This air is stopped when it hits the voice box and makes the opening between the vocal cords close very suddenly. This is what produces the sound of the hiccup.

SCIENCE NEWS – Discovery of An Underground Ocean

Earth’s Underground Ocean

In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.

An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.

Continuing our series on enterprising inventors of everyday things we take for granted, Sally Anne asks …

Who on Earth invented…the Pedal Bin?!

You’re carrying something to the bin, your hands are full and you don’t want to spill it. Thank goodness for the pedal bin! Read on to find out about the inventor who tried to make life easier.

Ergonomics is the science of making equipment which fits and works with the human body. This basically means making things work as easily and as conveniently as possible. Dr Lillian Gilbreth was a keen inventor who believed in finding the easiest way of getting things done. As such, she invented a range of gadgets to make jobs easier, including the pedal bin in the 1920s. Now we have to admit, pedal bins aren’t very exciting, but Lillian’s life definitely was.

My hands have no feeling.

My feet up to my lower thigh is numb. My stomach and chest is icy cold. I feel so light-headed I might as well faint. I have propped up my rigid body by a peeling black-painted gate which is pricking my back.

Someone stole my blanket, and now I am as good as a chunk of ice.

What is a Stick Bomb?

11-year-old Andre Jefferson explained stick bombs as being, ‘a kinetic chain reaction that is weaved together with jumbo popsicle sticks, that creates tension, and when you take one of the sticks out, it releases potential energy and makes it pop up about this high’.

If you are thinking ‘What?’ then watch the rest of his TEDx talk to find out what a ‘Stick bomb’ is and what makes them jump.
