EXPLOSIONS: THE BIG PICTURE An explosion happens when something bursts with great force. Explosions make a lot of noise. They can damage buildings and kill or injure people.
FOCUS Find the answers to these questions. 1. What do you do when you ‘cook off’ a hand grenade? 2.Why did the Chinese put cannons on a wall? 3.What is a tin fish?

ZOOMING IN …
The deadliest bomb of all.
Watch out for booby traps!
6
Torpedoes home in on their target.
Powerful pirates liked powerful guns. Take aim and throw!
This bomb bounced!
Defusing bombs – a dangerous job.

CANNONS The Chinese were the first people to use cannons. They put about 3,000 small cannons on the Great Wall of China. They fired the cannons at their enemies. Later, people used huge cannons on land and at sea. Merchant ships had cannons – and so did pirate ships!

Firing a cannon It took a team of soldiers to load and fire one cannon. It was a dangerous job and the soldiers followed step-by-step instructions.

HAND GRENADES Hand grenades are small, hand-held bombs. Soldiers carry them as part of their kit. Hand grenades are packed with explosives. Soldiers throw them when the enemy is close by.

SOLDIER HAS LUCKY ESCAPE! Jed Brown, 21, is a soldier fighting in France. He had a lucky escape last week. His mother, Mrs Coral Brown, said: ‘It’s all here in Jed’s last letter. There were some Germans in a dugout. Jed’s commanding officer told him to throw a hand grenade into the dugout. Jed threw a grenade but it didn’t explode. Suddenly, the Germans threw it back again! Jed kicked the grenade out of the way. It exploded but luckily nobody was hurt. Jed says he’ll remember to cook off the grenade next time!’
THROWING A HAND GRENADE 1. Pull the pin out. 2. Wait a few seconds. (This is called ‘cooking off’ the grenade.) 3. Throw the grenade at the enemy – they won’t have time to throw it back! 16
17
Pulling the pin The first British hand grenade was used in World War One. Soldiers still use hand grenades today. This is what a British 36 grenade looks like inside:

Grenade can only explode if you pull the pin out.

BOMBS Many different bombs were invented in World War Two. There were ‘hot’ bombs – these burned at a great heat when they exploded and set fire to buildings. There were also ‘bouncing bombs’. British pilots dropped these bombs to destroy enemy dams.
21
The Dambusters Raid PILOT 1
I can see the dam. Over.
Sound of machine-gun fire PILOT 2
The Germans have seen us. They’re firing at us. Over.
PILOT 1
I’m dropping the bomb. Bomb away!
PILOT 2
(worried): You dropped it too soon. The bomb’s bounced over the dam. Over.
PILOT 1
Try to get closer with your bomb. Over.
PILOT 2
OK. I’m dropping it now. Bomb away!
PILOT 1
(excited): Good work – it’s bounced down the face of the dam and exploded.
PILOT 2
(pleased): The Germans will be short of water for a while. Over.
PILOT 1
And it will stop their factories working, too! Over.
PILOT 2
OK, let’s get out of here!
22
The pilots get ready for action.
The dam explodes.
23
Bouncing bombs The bouncing bomb was invented in Britain by Barnes Wallis. It was built to skip over water, slide down the face of a dam and explode. The Dambusters Raid took place at night on the 16th May 1943. Nineteen Lancaster bombers were sent to destroy three German dams. The dams made power for factories in Germany. The bouncing bombs damaged two of the dams.
24
BOMB FACT The Germans invented a flying bomb in World War Two. It was called the V1. The ‘V’ stood for Vengeance!
25
CLOSE-UP: BOMB DISPOSAL A bomb that hasn’t exploded is very dangerous. Special bomb disposal teams are called in to defuse bombs. Bomb disposal experts often defuse bombs by hand.
26
27
Bomb disposal teams can also defuse bombs by remote control. This is safer for the team. They use a remote control vehicle.

TORPEDOES Captain David Bushell invented the first torpedo in 1776. Torpedoes were widely used in the First World War. A torpedo is shot under the sea to hit a ship or a submarine. It explodes when it hits its target.

Falklands War 1982 Report on the sinking of the General Belgrano – 2nd May 1982 Report by Dan Green – British submariner
I was on duty when an Argentine ship was spotted. It was the General Belgrano. We got orders to attack the ship. We attacked it with torpedoes from our submarine. Two of our tigerfish torpedoes hit the General Belgrano. I saw lots of explosions coming from the ship where the torpedoes had struck. The General Belgrano began to sink. I found out that there were about 1,000 people on board. I also found out that many people were killed. Some people escaped in lifeboats but the seas were cold and there were high waves. We saw five Argentine warships looking for survivors. I don’t know how many people survived.
32
33
Tin fish The torpedo was named after an electric ray fish. Torpedoes are sometimes called tin fish. A torpedo is a large tube with a warhead inside. The tube carries the warhead to its target. When the tube hits the target the warhead explodes. The inside of a torpedo looks like this:

LANDMINES A landmine is a bomb that’s buried in the ground. It explodes when somebody or something moves over it. People lay landmines under big areas of ground called minefields. Many people want to ban landmines. They injure and kill innocent people long after a war is over.

Clearing minefields There are many landmines buried all over the world. Clearing landmines is a slow and dangerous job. Some minefields have maps to show where the landmines are and these are easier to clear. But many minefields don’t have maps.
40
This is a landmine clearing tank. It has metal rollers that beat the earth in front of it. If there is a landmine under the earth it will blow up.
41
ATOM BOMBS Atom bombs make more powerful explosions than any other bombs. One atom bomb can kill thousands of people. An atom bomb explosion gives off radiation. The radiation harms people for years after the explosion.

Atom bombs in World War Two In 1945, the Allies dropped atom bombs on Japan because they wanted Japan to surrender. The first atom bomb was called Little Boy. It was dropped on Hiroshima on 6th August. It killed 138,661 people but Japan didn’t surrender.

46
ATOM BOMB FACT Little Boy was 2,000 times more powerful than any other bomb used in World War Two.
Little Boy Fat Man
The second atom bomb was called Fat Man. It was dropped on Nagasake on 9th August. It killed 73,884 people and this time Japan surrendered. World War Two was finally over.
