Jeanna went to a store that sold glass pottery. Near the register was a floating glass cup that was spinning, like the globe we saw..

To make it float they attached a small black disc to the bottom of the cup and set it on the center of the display box. When the box was plugged in, it made the cup float. The display was meant to make people look at the cup.

Jeanna decided that the box and the little black disk on the cup must be some kind of magnets.

She thought about what design problems the floating display was most likely made to solve. Which of the following is a good reason to use a floating display?

• It causes more people to look at the swan.

• It keeps the swan from being stolen.

• It makes it look more interesting.

• It lets people see all the sides of the cup.
