Friction can be quite strong. Dr. Boyd shows you just how strong it can be with this demonstration.

In todays session I take you through a 5 minute warm up routine for you and your class to follow along to, to help warm up for PE, specifically the shoulder muscles. I educate you through the different muscles used, as we...

Verona Rupes, found on Uranus' moon Miranda, is 20km tall! But because Miranda is so small, and its gravity so weak, would you survive falling off it? Astrum answers!

Tempered glass is stronger than regular glass and can withstand higher temperatures. It is also manufactured in a way that causes it to break into smaller pieces, which is safer than regular glass shattering into large shards. Unlike...

Glass is made by heating sand (mostly composed of silicon dioxide) until it melts and turns into a liquid at a high temperature of around 1700° Celsius. When the molten sand is allowed to cool, it becomes an amorphous solid, featuring...

Babies have a tight grip because it is a bodily reflex known as the Palmar Grasp Reflex (or simply the grasp reflex), which is typically observed in infants. You can elicit the grasp reflex by stroking your finger or any other object in...

Cell phones require network coverage to make calls. However, if the usable strength of the mobile network of your service provider (the manufacturer/company of the SIM card that you are using) is not good enough at the place where you’re...

The difference between air-drying and tumble-drying is that air-drying keeps the cellulose fibers from reforming their hydrogen bonds more effectively, which makes the towel feel a bit fluffy. Tumble drying, on the other hand, causes the...

A baby is born with around 300 bones, whereas a grown adult has 206 bones. Cartilage, a rubber-like padding that shields the ends of long bones at the joints, is the reason behind this. Babies are born with more cartilage (than bone),...

The pH scale is used to determine whether a substance is acidic or basic, and to calculate how strong a chemical it is. A pH value is a number that ranges from 1 to 14 for most common chemicals, with seven being the middle or neutral...

A strong acid is one that is fully ionised in solution.
