Bic writing supplies are widely used around the world, from office stationary to back to school essentials, pretty much everyone has owned a BIC product at one point. Most people assume that the hole at the end of the lid is to keep the pen from drying out or to balance the pressure inside the pen. This is not the only reason why BIC has incorporated this tiny yet efficient hole. The hole is designed to allow the passage of air if someone accidentally swallows it and it blocks their windpipe. Most users of BIC ballpoint pens have the habit of chewing on the lid.

BIC said on its website: “In addition to help prevent the pen from leaking, all our BIC caps comply with international safety standards that attempt to minimize the risk of children accidentally inhaling pen caps. Some of these vented caps, like that used for the BIC Cristal, has a little hole in the top to comply with the existing safety standards”.

According to the Independent, almost 100 people every year in the United States reportedly choke on the lids after accidentally swallowing them.

If you’re a frequent traveler, you might have noticed the small holes in the windows of airplanes. The little hole near the bottom of the window is called a breather hole or a bleed hole, and it serves an important safety function. If you look carefully, you can see that a typical passenger cabin window has three panes, typically made of acrylic materials. The innermost pane is called the scratch pane, and its function is merely to protect the middle pane.

The middle and outer pane are the most important ones. When an aircraft ascends, the air pressure drops in both the cabin and the outside air. The outside pressure however, drops much more than the inside. So, the aircraft’s pressurization system works around the clock to keep the cabin pressure at a safe and comfortable level. The outer window panes are designed in such a way that it contains this difference in pressure between the cabin and the sky.

In an unlikely event where the outer pane fails, the middle pane takes over and the passengers might feel a small leak of air through the breather hole. This is normal and the cabin’s pressurization system will cope with it. The hole in the inner pane also regulates some of the pressure difference so that the outer window doesn’t have to do all the work. It also prevents the windows from fogging up.

Almost all measuring tapes include a metal stub with a small slot on the end known as a “nail grab”. The purpose of this feature is if you’re measuring a flat surface and don’t have anyone to hold the other end of the tape, you just need to hammer in a nail or insert a screw and hook the end of the tape onto it to get a clear and accurate measurement. Also, some metal stub ends are serrated, which can be used to make a marking without the need for a pen or pencil.

10. The brushes on the sides of escalators are not for polishing shoes. The tiny bristles are a safety feature that prevents clothes and bags from getting stuck in them when people stand too close to the sides.

Every escalator is embedded with tiny bristles on both sides. Although similar to shoe cleaning brushes, they are installed as a safety precaution despite their apparent similarity. Also known as escalator skirt de?ector brushes or escalator safety brushes, their main function is to promote passenger safety by gently guiding passengers away from the skirt panels. If your shoes, clothes, bags or any other object gets too close to the edge, they could get trapped in the gap between the stationary skirt panels and the moving steps on escalators; causing serious mishaps or injuries. This safety feature is necessary to help reduce the chance of step-to-skirt entrapments.
