Many of us assume all cardboard boxes are the same and pretty basic, but it is their formation that makes them suitable for different uses.

The 3 most common types of cardboard used in packaging are, corrugated box, folding cartons and the rigid box. Each box starts off the same with cardboard sheets as the base but then enhanced further to suit its usage.

You’d be surprised how an extra layer of paper can make a huge difference to the strength and durability of the cardboard box.

Traditionally, consumers have relied on water shoes to protect their feet from rocks, provide traction and drain water during all sorts of outdoor activities. But similarly to Crocs, they've usually been a purely functional piece of footwear. "Since they were mainly used for water activities like kayaking, hiking and swimming, water shoes have not been regarded for their style," Sara Skirboll, RetailMeNot shopping and trends expert, told TODAY Style.

The Tough Spun has very interesting properties. As it is a fine pattern of thin threads, there are clear spots along the material where direct light can shine through. This means that it produces a combination of both hard and diffuse light. You can see this illustrated in the images of the geometric shapes from our test, as both the umbra and penumbra of the shadows are well-defined.

The Coronavirus Disease 2019 (COVID-19) pandemic has caused an increase in the use of pulse oximeters, and a recent report (Sjoding et al.External Link Disclaimer) suggests that the devices may be less accurate in people with dark skin pigmentation. The U.S. Food and Drug Administration (FDA) is informing patients and health care providers that although pulse oximetry is useful for estimating blood oxygen levels, pulse oximeters have limitations and a risk of inaccuracy under certain circumstances that should be considered.

Mishandling of workplace materials is the single largest cause of accidents in the workplace. Fortunately, most of these accidents are avoidable. With wire rope slings playing an important role with cranes, derricks, and hoists, it’s important to understand how to make a proper selection.

A wire rope sling is made of wire rope. It is composed of single wires that have been twisted into strands. These strands are then twisted to form a wire rope.
