Answer:
H₂O might be the most familiar chemical compound on the planet. Many people know that water is H₂O, but most wouldn’t think about what that means in a chemical sense. Water is a remarkable molecule made of two Hydrogen atoms bound to a single Oxygen atom: H, H, and O. Water’s special properties give us life as we know it, and we’re mostly made of it too. It’s less dense as a solid (ice) than as a liquid, which has major consequences for the planet and its climate. Water is also really good at storing heat, and it stays liquid over a wide range of temperatures, also very handy for life as we know it.
In short: water is amazing: but can we destroy it? Yes. With just two regular pencils and a 9V battery, you can actually break water down into it’s Hydrogen and Oxygen components, and watch them boil away as bubbles of gas. This is fundamental chemistry available to anyone at home, with stuff you might have lying around.
You’ll need some salt, a 9V battery, a drinking glass (or other transparent container), two pencils, and some wire. It ’s best to get some cheap cables with crocodile clips (I bought these ones from Amazon), since they make it much easier.
