LIPSTICK GUN In 1965, American officials arrested and searched a person acting suspiciously at an inspection point in West Berlin, Germany. They found a normal-looking lipstick holder. But when they opened its case, they realised it was actually a 4.5 mm pistol capable of firing a single bullet. The weapon, nicknamed ‘Kiss of Death’, is now on display at the International Spy Museum in Washington DC, USA. Disguised guns were often used by Soviet agents during the Cold War. WRISTWATCH CAMERA In the late 1940s, West German engineers developed a miniature spy camera that was disguised as a wristwatch. This was decades before the invention of digital cameras so concealed beneath the camera's lens was a tiny roll of photographic film that was capable of taking eight photographs. Secret agents…

GAVIN PRETOR-PINNEY Founder of the Cloud Appreciation Society Question: How much does a cloud weigh? From Emily, age 7 Answer This partly depends, of course, on how big the cloud is. Because clouds, as you've probably noticed, come in many different shapes and sizes. So let's imagine that we're trying to calculate the weight of a medium-sized cumulus cloud, which is the type of white, fluffy cloud that you often see on a sunny day. First, we must estimate the cloud's size. And a medium-sized cumulus cloud might be 1 km long, 1 km wide and 1 km high, giving it a total volume of one cubic kilometre. Next, we need to estimate the weight of all the water droplets inside the cloud. Scientists have found that a cubic metre…

USING CODES MORSE CODE Morse Code is a system of communication that was invented in the 1830s by the American artist and inventor Samuel Morse. It uses dots, dashes and spaces to represent letters, numbers and punctuation. Morse Code was originally designed as an electronic form of communication. A machine called a telegraph converts the code into a series of electrical signals which are then converted back into the original message by the telegraph that receives them. Morse Code was a key form of communication used by both intelligence agencies and the military during the Second World War, when it was used to transmit important messages, most of them already written in other secret codes. PIGPEN CIPHER Pigpen cipher, which is also known as tic-tac-toe cipher, is an ancient code…

It was raining. It had rained the day before, and the day before that, too. For millions of years, life swarmed in the seas and rain hammered the land. There was nothing to see except lifeless rock and mud. Then, about 470 million years ago, a little bit of green appeared. The first land plants were growing near the water's edge. These were squidgy liverworts and mosses. They had evolved from green algae, a water plant still around today. Like all plants, these used photosynthesis to make the energy they needed. Next came a new type of plant that could grow much taller. They had a system of tubes to carry food and water from the ground to the tops of their bodies, a bit like the way we transport…
