A ceramic tile cutter is like a big, special pair of scissors for cutting tiles. You know how you use scissors to cut paper? Well, tiles are much tougher than paper, so you need a special tool to cut them.
The ceramic tile cutter has a big, flat base that you put the tile on. Then there is a big, sharp wheel that you use to score a line on the tile where you want to cut it. Scoring means making a little crack in the surface of the tile. It's kind of like drawing a line with a pencil, but instead of leaving a mark, you're making a little crack.
Once you've scored the tile, you'll need to break it along the score line. That's where the ceramic tile cutter has this cool lever arm. You push down on the lever arm, and it puts pressure on the tile along the score line. This pressure helps the tile crack along the line you scored.
Now you have two pieces of tile! Sometimes you need to make more than one cut in a tile, so you just position the cutter where you want to make another cut and start the process again.
It's important to be careful when using a ceramic tile cutter because the wheel is very sharp, and if you're not careful, you could cut yourself. You also want to make sure you're cutting in the right place, so you don't waste any tiles. So always use adult supervision when using a ceramic tile cutter.
