Magic Torch Light

One day, when Josyne is walking back from school, she sees someone is selling something by the roadside. She goes to see if he sells any sweet, but the man is actually selling all kinds of used things.

Josyne notices that there is an old torch light selling for 50 cents. She thinks she really needs a torch light as she is walking to school quite early in the morning. The sky is still dark especially when it is raining. So she pays the money and brings back the torch light.

Josyne notices that there are two buttons - yellow and green, on the torch light. When pressing the yellow/green button, yellow/green light beams out from torch light. 

One day, when Josyne is doing her homework at night, suddenly there is a blackout. So she takes out the torch light and sets the yellow button, beaming on her exercise book. After 10 seconds without moving the torch light, suddenly she notices that her exercise book becomes bigger and bigger! Josyne is shocked and quickly turns off the torch light.  

"What has happened?"

Josyne takes out a piece of biscuit and beams the yellow light on it. After 10 seconds, the biscuit grows bigger and bigger! She then eats the biscuit, and it tastes normal. Josyne is happy with the torch light. She knows the magic will only work when she beams the light to an object without moving for 10 seconds. As she is from poor family, where mummy only gives her a small piece of biscuit for the breakfast, the torch light is very useful to help her to eat more biscuit so that she won't feel hungry.
