You will need
• A coin
What to do
Place the glass on a table, with the coin underneath the glass. Looking though the side of the glass (not directly overhead), see the coin at the moment. Now keeping your eye on the coin, slowly fill the glass with water.
What to look out for
As the glass begins to fill with water you’ll notice the coin seems to disappear. This is due to the refraction (bending) of light as the light passes through the water. Move your head and look down from directly overhead and you’ll notice the coin is still where you left it – right underneath the glass.
