Vanishing Car

Now there is probably an explanation for this, which I am sure my teenagers will explain to me in very simple terms slowly. But why when following this tanker can I not see my car, the shadow of my car seems to be there. But the road behind the tanker looks very empty.

Anyway thought that the reflection looked so cool.

Leaves, Bubbles and Reflections

While taking a pic of this leaf in a bucket, I managed to catch this drip, as it splashed in.
If you look very carefully you can see the reflection of me and my camera in the bubble.
