Inventions from COVID-19

-
Necessity is the mother of invention. With the cases of coronavirus rising in Africa one of the many precautions everybody is advised to take to help curtail the spread of the virus is constant hand washing.
It is saddening that there were no efficient hand washing buckets. Hand washing buckets which one needs to turn the taps on/off is not efficient because it also encourages the spread of the virus. Some many people have tried to solve this challenge by constructing foot controlled hand washing buckets. Here are some pictures ;

With the invention above you do not need to touch any knob to turn on the tap.
There are some other smart inventions;

Journey to the Red Planet: Dream or Reality

      Mars, (commonly known as the red planet), is the most probable planet after earth to sustain life. However, there are a lot of challenges we need to overcome in order to make a trip to this planet. Here are a few of them.      Considering discoveries made so far, the planet is known to contain water. The water is however in the form of ice as the atmospheric pressure of mars is less than 1% of ours here on earth. The amount of water on mars (as ice and hydroxyl ions) if converted, could cover the entire planet's surface to a depth of about 600 meters.      The atmosphere of Mars consists of about 96% carbon dioxide, 1.93% argon and 1.89% nitrogen along with traces of oxygen and water. The atmosphere is quite dusty, containing particulates about 1.5 µm in diameter which give the Martian sky a tawny color when seen from the surface. This is obviously not the kind of air we are used to inhaling, besides only a limited ...

You have been getting it so wrong

-
The next time you pull up directly behind someone at a traffic light and you're behind the wheel, look at the guy's driver side side view mirror in front of you. Do you see his face in the mirror? Of course you do. If you don't, he probably knows how to set it correctly. Do it with the next guy and the next. You'll find most people don't. The problem is, people aim the side views on both sides until they see their own rear fender. WRONG. You need to see the lane along side your car. In fact, on a three lane highway from the center lane, you should be able to glance at your overhead rear view mirror and see the guy's car directly behind you. As he's passing you on the right (i know he's not supposed to), as he disappears from view from your center mirror, you should already be picking the nose of his car up on your passenger side view mirror with a visible overlap between the two mirrors. Same thing if he passes you correctly to your left. As he di...
