Nitrous oxide

Nitrous oxide is a special gas that is sometimes called "laughing gas." It's made up of two different things: nitrogen and oxygen.

This gas can make people feel a little bit funny or silly when they breathe it in. When you breathe in nitrous oxide, it makes your brain feel a little bit different than usual. People sometimes giggle or feel like everything is funny when they breathe it in.

One important thing to remember is that nitrous oxide should only be used in a really safe way, like when a doctor is giving it to you at the dentist. It can be dangerous if you breathe in too much of it or if you don't use it safely. So it's very important to only use nitrous oxide when it is being used safely by a doctor or other professional who knows how to use it correctly.
