Caviar or fruity ball? Whatever you like! Here’s a rundown of how to spherify your own edible bubbles and why they could help to reduce waste.

Environmental scientist David Keith proposes a cheap, effective, shocking means to address climate change: What if we injected a huge cloud of ash into the atmosphere to deflect sunlight and heat?

Your digestive system impacts the rest of your body in all sorts of unexpected ways, from keeping your heart healthy to literally making you feel happier.

The list of vitamins can be kind of confusing, what with all those B vitamins and a random K thrown in. But every name has its story.

Vitamins are the building blocks that keep our bodies running; they help build muscle and bone, capture energy, heal wounds and more. But if our body doesn't create vitamins, how do they get into our system? Ginnie Trinh Nguyen describes...

One of the most important factors when it comes to mixing any gas with a liquid is solubility, and carbon dioxide is highly soluble in water. In fact, it's the most soluble of the common, non-toxic gases with high solubility. To give you...

Water especially the one which flows through the pipe contains atmospheric gases, such as nitrogen and oxygen, dissolved in it. As the glass filled with water sits out for a few hours, its temperature rises slightly (water gets warmer),...

To make a solution of something by mixing a soluble substance into a solvent, such as salt into water.

The properties of water and its uses, depend on its mineral content. What minerals are found in water and how do they affect it? Chemistry - Periodic Table - Learning Points. Water contains dissolved mineral ions, such as sodium, calcium...

Why and how do substances dissolve? Discover what happens when you create a solution. Chemistry - Atoms And Bonding - Learning Points. A solution is the mixture formed when a solid dissolves in a liquid. A solvent is a liquid that can...

The properties of strong acids and alkalis can be extremely harmful. Where do we find them, and how can we tell how acidic or alkaline a substance is? Chemistry - Reactions - Learning Points. Bases neutralise acids, and if a base...

We use filtration and evaporation to separate out a mixture of water, sand and salt. The sand is removed using filtration, as it did not dissolve in the water. The remaining solution is heated until the water evaporates, leaving behind...

We use chromatography to see what colours make up the ink in different coloured felt tip pens. Different coloured dots are drawn on a piece of chromatography paper and this is lowered into a chromatography jar containing water. We watch...

We use mercury(II) chloride solution and potassium iodide to demonstrate a precipitation reaction. Saturated potassium iodide solution is placed on a magnetic stirrer and the speed is set so that a vortex is created. Mercury(II) chloride...
