Hooke's Law

Such scales are a clear example of how Hooke's law works☝🏻

According to the law, one kilogram of cherries extends the scales by one division, and two by exactly two, of course. The law states that the force applied to an elastic rod (in our case the spring in the scale) is directly proportional to the elongation of the body.

Mantiz — a folding pocket laptop stand

Made of aluminum alloy, it measures 18.6 mm x 116.8 mm x 33.6 mm when folded and 211.8 mm x 277.5 mm x 74.5 mm when unfolded. The weight is only 160g.

The stand can change height from 76.2mm to 116mm allowing you to choose the best viewing angle for your laptop screen. Moreover, the manufacturer says that the novelty will help avoid problems with posture as well as neck pain.

And the last argument is that the gadget will save your device from spilled liquid on the table.

What water sounds like without air. Air is pumped out of the tubes, but it's not a vacuum, it's water vapor.

Penguins do not need fresh water — they are able to drink salty seawater, as special glands in their body filter out salt. 🐧
