A solid should look solid, and this block looks like trapped smoke. Your eye flags it as wrong before you can say why. The title insists it really is a solid, and the gap between the word and the picture demands a click.
How the packaging works
Title

Thumbnail

The transferable lesson
An image that contradicts its own noun forces the click
