The clue is the key to this puzzle.

Remember, there's a large glass water tank next to the door. How might that help you?

US Version

Let's take a look at these balls with panels attached lying on the floor. The cords connecting the panels are all different lengths. Additionally, the balls are made of two different materials: wood and metal.

How do these details fit in?

Have you worked out what "ask the water" means yet?

Putting all the balls lying on the floor into the tank will cast some light on the situation.

US Version

Imagine putting the balls into the water tank and viewing them through the glass. The panels attached to the wooden balls will just float on the top, so you won't see them. The metal balls will sink, so you'll only see panels attached to those balls.

The lengths of the cords also differ, so imagine what order the panels would appear in from top to bottom. Might this be the code to get in?

UK Version

Imagine putting the balls into the water tank and viewing them through the glass. The wooden balls and the panels attached to them will float at the top, so you won't see the numbers. The metal balls will sink, so you'll be able to read the panels attached to those balls.

The lengths of the cords also differ, so imagine what order the panels would appear in from top to bottom. Might this be the code to get in?

## Solution

### Incorrect

Think about the clue some more. What could "ask the water" mean?

### Correct

Correct! The door is open!

US Version

The code was 9594. If you drop the balls into the water tank, the wooden balls and their attached panels will just float on the top, while the metal balls will sink to the bottom, leaving the important panels in the middle.

The length of the cords tell you the order of the numbers, so you have to enter them from top to bottom, the same way you would see the panels floating in the tank.
