You buy a chocolate bar in a package that claims the thing is 25% bigger than its previous version. Then you pick a shampoo that has "only natural ingredients" on the bottle and costs surprisingly little. Ooh! Now stop. Do you really get a great bargain or is it just manufacturers fooling you? Think twice — marketing experts are talented manipulators! For example, a bag or a bottle itself may look bigger than others produced by the same brand, but its weight can be absolutely the same! Some manufacturers aren't strangers to using optical illusions to make customers think there is more product than in reality. Empty space inside boxes, inflated plastic bags, labels stuck at the top of glass bottles so that you don't notice they are half empty...

Just don’t try to make another breath while swallowing that pizza — only babies are capable of that and inhaling at the same time. Okay, there's the pharynx, where air and food come together. It’s a kinda sorting stage. Epiglottis makes sure that food goes where it belongs, to the esophagus. Next are the larynx, the trachea, and finally to the two bronchi, one going to each lung.

Welcome to space! Let's see what a typical day in the life of an astronaut looks like. Every minute and every second of an astronaut’s day in space is planned.

A couple of days later, heavy fog covered everything in sight. Could it all be a coincidence, or was the writer psychic? Let's find out!

Spaceships are not like your regular cars running out of fuel on the highway. Space is like a friction-free paradise! Unlike ships in water that need a constant push to keep going, spaceships have got it all figured out. Once those engines are turned off, their momentum takes over and propels them forward at a steady pace. It’s a cosmic roller coaster with no brakes. But does it mean spaceships never run out of gas?
