We know that light travels
We know that light travels in straight lines. But do you visually show this? You will need a toy laser and some chalk dust. In a dark room shine the laser on the far away wall and you will see a spot on the wall. Now with the blackboard duster tap some chalk dust on the path of light. The chalk particles will disperse the light and the beam will appear going in a straight line!! This very spectacular experiment always wins a loud applause of claps from the audience!
