Keep reading to find the answers to these questions written by Whizz Pop Bang’s expert team of scientists, and discover why endless questioning is a really important part of your child’s development (even when finding the answers can be challenging!)

Why do children ask so many questions?

Questioning trusted adults is a crucial way for children to understand, and form their own ideas, about the world around them. But it can be exhausting at times – Paul L. Harris, Professor of Education at Harvard, estimates that a child asks 40,000 questions between the ages of two and five.

Every issue of Whizz Pop Bang is packed with fascinating facts, simple scientific explanations, and experiments designed to demonstrate the answers to some of your child’s burning questions. Our team of expert scientists (including our all-knowing robot, Y) are on hand to answer our readers’ questions every issue, too – so if you can’t find the answer to your child’s latest conundrum here, why not email us at and see if we can help?

Meanwhile, here are the scientific explanations of a few wonderful questions we’ve been asked recently…

Why do carrots and other vegetables grow underground and not above ground?

We eat at least six different parts of plants. Sometimes we eat the leaves (e.g. lettuce and kale and cabbage). Sometimes we eat the stems (e.g. celery, asparagus, and rhubarb). We eat seeds, such as sunflower seeds and sweetcorn. We eat flowers (such as broccoli) and fruit. And we also eat roots and tubers. A carrot is the main root (or tap root) of a carrot plant. As well as soaking up water and minerals from the soil, it acts as an underground food store for the plant. That makes it a great food for us, too!

Why aren’t rivers salty, like the sea? 

Rain isn’t salty because when water evaporates, anything dissolved in it is left behind. Rivers are topped up by this rainwater, so they aren’t very salty either. But rivers do pick up some salt as they rush over rocks. Eventually, this salt ends up in the sea. Rivers around the world carry 3.6 billion tonnes of salt to the oceans every year! But the oceans don’t just get saltier and saltier, because about the same amount of salt sinks to the seabed each year, becoming part of new rocks.  

Why do bouncy balls bounce and don’t just stick on the ground like a rock?  

Unlike rocks, bouncy balls are made of elastic materials, such as rubber. Elastic materials are flexible – it’s easy to change their shape. But they return to their original shape after being squashed or stretched. When the ball hits the ground, it is squashed out of shape. Some of its movement energy is changed into elastic energy, stored very briefly inside the ball. Once the ball has come to a stop, this elastic energy is released as the ball returns to its original shape. The ball pushes against the ground and the ground pushes back, sending the ball back up into the air.  

Why do we need the moon?

About 4.5 billion years ago, a giant space rock the size of Mars crashed into Earth and knocked off a chunk of our planet. This chunk of rock became the Moon, and it still orbits Earth, roughly once every 27 days. The Moon is big enough and close enough that its gravity causes bulges in Earth’s water that sweep across the planet’s oceans and seas, causing the tides. Many living things have adapted to depend on the tides for shelter and food. Humans who live near coasts also depend on the tides for catching certain fish and sea creatures, and for sports like surfing. But if the Moon suddenly disappeared it wouldn’t just be coastal life that was disrupted. All life depends on the Moon, because it helps to keep Earth’s climate stable.

Why don’t human eyes glow like cats’ eyes do in the dark?

Want to know why cats’ eyes glow? They shine in the dark because each eye has a thin layer of crystals at the back. This layer is called the tapetum lucidum. Its job is to bounce light back into the cat’s eye. This extra light helps cats to see better in the dark. Lots of other crepuscular and nocturnal animals have this light-reflecting layer too. Most animals that are awake in the daytime don’t, including humans. However, you’ll sometimes see human eyes glow red in a photograph, when the bright light of a camera flash bounces off the back of our eyes. 

Why do ice cubes stick to your fingers and ice lollies stick to your tongue?

Heat always moves from a warmer place to a colder place. When you lick a lolly, heat flows from your toasty tongue to the, erm, icy ice. If the lolly is very cold, the saliva coating your tongue drops below 0°C before your body can warm it back up. The saliva freezes and becomes part of the chunk of ice along with the lolly! The same can happen with wet fingers and a very cold ice cube. Never pull your skin away – use room temperature water to melt the ice and set yourself free! 

Why do your teeth chatter when you’re cold?

Want to know why do we shiver? Deep inside your brain, your hypothalamus (say hi-po-thal-a-mus) is busy monitoring your core body temperature. It’s your inbuilt thermostat! But instead of turning on the central heating when you drop below 37°C, the hypothalamus triggers reactions that help keep your organs warm while you find shelter! One of these is shivering. Muscles produce heat as they contract – think how warm you get when you exercise. Shivering is your body’s way of making your muscles contract and relax as you stand still. As your jaw muscles shiver, your lower jaw moves up and down quickly, bumping your teeth together. 

How does fire form?

Heat is one part of the ‘fire triangle’ – the three things needed for a fire to start. The other two are fuel (something to burn) and oxygen (from the air). The heat – from a burning match, lightning or even the Sun’s rays – starts a reaction between the fuel and the oxygen. This produces gases, including water vapour and carbon dioxide. It also releases energy as heat and light. This heat keeps the reaction going until the fuel or oxygen runs out, or the fire is cooled.  

Why do people have different accents?

People can speak the same language with very different accents. This is because we aren’t born speaking a particular language, but with a brain that is brilliant at absorbing and imitating any sounds it hears. This amazing ability to learn is why people tend to speak with the accent they heard most often when they were very young. By the time we are a year old, we are less able to hear different sounds and it becomes harder to pick up a new accent. The ability to imitate stays with us though, so accents can change as people move around, or even during a conversation. In fact, scientists have found that mimicking each other’s speech patterns can help two people to understand each other better, and make friends more quickly.

Watch our young reporter morph into a dinosaur!

Two of our young reporters, Ash and Owen, were recently invited to take a tour of ILM (Industrial Light & Magic) studios to see their awesome movie technology. Here’s their report of the day…

“We were so excited to be visiting ILM in London! This is the studio where they work on the visual effects behind some of the biggest films in the world, like Avatar and Star Wars. 

When we arrived, we were invited to have some drinks and nibbles in the green room, but we were too excited for that, so we were led straight through! First was a big room full of boxes and boxes of equipment and props, all labelled and catalogued so that they can easily be found and taken out on set.

Here we all are standing in front of an ILM StageCraft LED screen

We then went past some dressing rooms where film stars get changed, and into the studio where the magic happens. The main studio was a large warehouse space with three massive LED screens and a vast padded floor. Behind us, a team of technicians were working away on a row of computers. 

The tech team working their magic

First, we learnt about ILM’s facial capture system, which is called Medusa. Medusa works by taking lots of photos of the actor. The actor sits in a chair that is surrounded by a bank of cameras. The actor has to make lots of different facial expressions and pull lots of silly faces! They have to say various sentences that have been designed to include all of the different sounds used in everyday speech, so that the computer can learn the shapes that their face makes when they are saying each sound. Using the Medusa software, a computer takes in all this information and creates a digital copy of their face which the tech crew can use to digitally create footage of the actor. This is useful for superimposing an actor’s face onto a stunt person’s body.

Next, I got to try on a motion capture (mocap) suit. These suits are made of grey fluffy fabric so that Velcro can stick onto them. After putting on the suit, I was then kitted out with lots of small reflective balls on Velcro pads. 

Owen in a mocap suit. ILM turned this toy sword into a light saber on the screen!

There are cameras all around the ceiling of the studio that emit infrared light and pick up the reflections of this light from the reflective balls on my suit. Computers can then track these balls to follow my every move.

With the suit on, the technicians were able to turn the screen image of me into lots of different characters. They made me into a robot with pistons for joints, a Stormtrooper, a velociraptor and a shiny humanoid, whose skin reflected whatever background they put me in.

The toy sword has become a light saber!
Owen became a Stormtrooper!

The suit was incredible, as the movements on the screen matched all the movements that I made in real time without any delay. My favourite was the velociraptor! 

The mocap suit translated Owen’s movements into those of a dinosaur!

Next, they showed us their virtual camera. This was an iPad with two Nintendo controllers attached on the sides. The iPad had been set up with a scene from Star Wars. The director could use the iPad as a virtual camera. When he walked around, it was as though he was holding a camera in the scene. With this contraption the directors can picture what different shots would look like inside a virtual world by seeing which shot looks good on the iPad.  

We got to take a look at a couple of virtual reality setups using VR headsets, which looked incredibly realistic. We were also shown how they could film a model of say an X-wing Starfighter and put it in front of a video of a fly-through. Viewing it through a camera lens made it look like the X-wing was really flying through the scene!

We learnt so much in this visit. It showed us just how incredible the world of computer generated imagery really is, and it was brilliant fun too! It was an experience of a lifetime – thanks so much ILM!”
