Answer 2

OK. Here's one you can try. This demonstrates the bending of light (refraction). Have a glass tank and make a tiny hole on the centre of one of the faces. Also have a toy laser with you. Fill the tank with water. When water starts flowing out focus the laser from the opposite face and you can see the light bending along the flow of water.

You will have to make the size of the whole big enough for water to flow out but still small enough to make the light bend. Happy experimenting.
