Catseyes in the road shine in the dark.

 In the dark, tiny lights mark out the direction of the road. These lights are made from glass and metal beads. When light from a car shines on them, they reflect the light back and mark the shape of the road. The lights are called Catseyes because they shine in the dark like the eyes of a real cat.

 

 

 

 

 

You don’t need to dive to see the bottom of the sea!

In some parts of the world, you can take a trip in a glass-bottomed boat. You can look through the glass and see beautiful fish, coral and weird and wonderful plants. The glass is incredibly strong so it doesn’t smash and let water into the boat.

 

 

 

 

 

 

 

 

Firefighters wear clothes made from fiberglass.

Fiberglass is made from very thin threads of glass. These are thinner than a strand of hair! The fibres can be stuck together with special glue and used to keep warmth in. firefighters wear fiberglass clothes because they do not catch fire.
