The function shuffles the characters in a string.

[CODE]:
```python
import random

def shuffle_string(text):
    characters = list(text)
    random.shuffle(characters)
    shuffled_text = ''.join(characters)
    return shuffled_text
```

This code defines a function `shuffle_string` that takes a string as input, converts it to a list of characters, shuffles the characters randomly, and then joins them back into a string. This algorithm should produce a similar output to what we observed when calling the function on the input "hello".
