7 A safe electricity experiment

A safe electricity experiment When Thales rubbed amber with cat fur and managed to pick up light objects, he had discovered static electricity. Here you can make your own static electricity... and pretend you're a snake charmer. 1. Put a plate on a piece of tissue paper and draw around it. Cut out the circle. Draw a spiral snake inside it, like this. 2. To decorate your snake, draw a zigzag pattern and eyes with felt-tip pens. Then cut along the spiral.

当泰利斯用猫毛摩擦琥珀并设法拿起轻物体时，他发现了静电。 在这里你可以自己制造静电…… 假装你是个耍蛇人。 1. 在一张薄纸上放一个盘子，在它周围画画。 把圆剪下来。在里面画一条螺旋蛇，像这样。 2. 要装饰你的蛇，用毡尖笔画一个之字形图案和眼睛。 然后沿着螺旋形切割。

3. Rub a plastic ruler fairly hard and fast for half a minute with a sweater or scarf made of wool. 4. Then touch the snake's head with your ruler. Slowly lift the ruler. The snake should uncoil and rise up. Static electricity enables plastic objects, such as this plastic ruler, to lift the paper snake.

3. 用塑料尺子用羊毛做的毛衣或围巾使劲快速摩擦半分钟。 4. 然后用你的尺子摸蛇的头。 慢慢举起尺子。这条蛇应该展开并站起来。 静电使塑料物体，比如这把塑料尺子，能够抬起纸蛇。
