Theme ~ Car

One night, YJ kept asking us these questions:

What car's engine made of?

What car's tyre made of?

What car's stearing made of?

Now I know why. They were having the car as a theme that day.

Children, this is engine.

This is car's tyre. Try to touch and see.. it is made of rubber.

This is exhaust pipe. It's hot! Don't touch!
