In large apartments and private houses, it is difficult in the evening and at night to walk along dark corridors or stairs and find the switch by touch to turn on the lighting. There is also an alternative — to buy autonomous “soft light” fixtures; they can be installed anywhere convenient for the owner. However, Read more…
How far can a person travel by pushing off the ground just once? If it is one step — on average less than a metre. If you build up speed and push harder, you can jump about four or five metres. So imagine our surprise when a modest, no longer young man walked into the Read more…
