Which material is the best at soaking up liquid?

Last week we did some Science work to help Discovery Dog. He needed to find a good material to mop up a mess that Naughty Nora had made on the kitchen floor.

First of all we made guesses about which materials might be the best. Then we tested our ideas to see whether our guesses were right.

We put some blue food colouring in the water so it would be easier to see. We poured it into a tray and used each of the materials to try and soak it up.

Which one do you think worked the best?
