Okay, so imagine a church that you usually go to every Sunday. It has a roof, walls, and a floor, right? Now, let's say that same church didn't have anything inside. It's like an empty box. That's what we call a "hollow" church.
You know how when you clap your hands or shout in a big open space, you can hear an echo? Well that's what happens in a hollow church. Because there's nothing inside, sounds bounce around and create echoes. It can be really cool to listen to!
But having a hollow church is not always a good thing. You see, churches are usually built to hold lots of people and help them focus on praying and listening to the priest or pastor speak. If there's nothing inside, it can be harder to hear what's being said, and it might not feel as special or important.
So, while a hollow church can be interesting to explore and make cool sounds in, it's not ideal for having church services. It's important to have things like pews, altars, and other decorations inside to help people feel connected to their faith.
