When you press the flush button, your wee, poo, toilet paper and water go down a pipe called a sewer. The toilet flushes the wastes down the sewer pipe. The sewer pipe from your house also collects and removes other wastes. This might be soapy water from baths and showers, or water left over from wa...

Space probably does go on forever, but the truth is we don’t know. Not yet anyway. That’s what makes this a great question, because science is all about finding answers to things we don’t know yet. So, what do we know about space? We know it’s big, really big. It’s big enough to contain t...
