Students Book pages 8&9 The Time Travellers 2 Read and listen to the story to find out if it is similar to or different from your story. THE EXPLOSION Alex read out the instructions for the next experiment. 'Add one spoon of yellow powder to the blue liquid,' he read. Phoebe followed the instruction. 'It's turned green!' she said. Patrick was not very impressed. 'Yellow and blue make green,' he said, 'everyone knows that!' 'Wait!' said Alex. 'There are more instructions. Now take some of the liquid and drop it on the brick.' Phoebe did this and the brick turned purple. 'Wow!' she said. 'That's amazing!' 'It's boring,' said Patrick. 'Can we do the next experiment?' For the next experiment, Patrick read and Alex followed his instructions. He put two spoons of white powder and one spoon of red powder into a test tube. Then he added some pink liquid. It quickly turned orange. 'Now pour some of the orange liquid onto the brick,' said Patrick. Alex did this and amazingly the brick started to get bigger. 'Wow!' said Alex. 'That's fantastic!' Mr Davis came to look at their experiment. 'Good work,' he said, 'but don't forget to read the instructions carefully for your next experiment.' 'That wasn't very interesting,' said Patrick. 'Let's do the next one.' 'OK, it's your turn to do it,' said Phoebe. She read the instructions. 'OK, we need some blue power, some green powder, some orange powder and some green liquid.' While Patrick was getting all the things together he knocked over a small cup of water. The water went all over the instructions. 'Careful Patrick!' said Phoebe. 'Oh no! There's water on the instructions now and I can't read a thing.' 'Let's ask Mr Davis for some more instructions,' said Alex. 'Don't be silly,' said Patrick. 'I've got everything here. We just need to mix it together and put it on the brick.'

'But we don't know how many spoons of each powder we need,' said Alex. 'Don't worry,' said Patrick, 'let's experiment.' Patrick poured all the blue powder into the orange and green powder. Then he added all the green liquid. Suddenly there was a big explosion and a bright red flash. 'Wow!' said Patrick. 'Now that was amazing. I think I added a bit too much liquid,' he laughed. Alex and Phoebe didn't think it was funny. 'What's that?' said Alex. He was pointing to a strange, glowing light. It was yellow and it looked like a kind of gate. 'It's really strange!' said Phoebe. The children walked towards the light and stepped into it. They were gone in a flash.
