Why is this the answer?

The answer is hole because this clever riddle uses a super smart word trick to make you think about something that is really just an empty space. When you first hear the question What gets bigger the more you take away from it?, your brain probably starts thinking about objects like toys or fruit. But a hole is special because it is not a physical object you can hold; it is the absence of something. It is just empty air where something else used to be. Think about what happens when you decide to dig in the dirt. Maybe you are outside with a shovel, trying to make a big home for a new tree or just a place to find worms. The first thing you do is scoop out a little bit of earth. When you do this, you have created a small empty space. That small empty space is your first hole. To make the hole bigger and deeper, you must keep taking away more of the dirt. Each shovel full of earth you remove is a piece of the ground that you are moving out of the way. The more earth you take away, the wider and deeper that empty space becomes. It is the removal of the dirt, the taking away of the material, that makes the hole grow. You are making the empty space take up more room. If you take away just a little bit of dirt, you get a small hole. If you take away a whole lot of dirt, you get a much bigger hole. The riddle is funny because it flips the normal rules we think of. For almost every other object, when you take pieces away, the object gets smaller. If you take bites out of an apple, the apple gets smaller. If you rip a piece of paper, the paper gets smaller. But with a hole, the opposite is true. You must keep removing the surrounding material for the empty space to expand. It is a fantastic puzzle that helps you look at a simple, common thing in a new and amazing way. It shows how a hole is defined by what is not there.
