1. Have you ever seen bricks that are used as a battery.
If not, then have a look at these electric bricks.
The bricks seen in the photo here are very smart. These are not only to build the walls of the house rigidly, but also used as a battery to store electricity.
With the electricity stored in these bricks, the lights in
the house can be lit, the fans can be rotated, the phones can be charged ...
and much more. Researchers at the University of Washington have made
ordinary bricks smarter. By coating ordinary bricks with an electrically
conductive polymer, these could be converted into batteries that store
electricity.
That in the future such bricks will reign supreme in
the field of construction, Researchers at the University of Washington
have found that homes built with these materials do not require an external
electrical connection. These bricks made of polymer coating cost only
RS 48 each.
2. You all must have seen the hole
in the washbasin. Have you ever thought of what might be the
purpose of hole on the side of a sink. Let's figure it out.
If the water tap
is left on while the drain also closed, then the opening will channel the
water down into the drain opening rather than spilling out of the
sink.
The overflow allows the sink to drain faster by introducing
air into the system.
3. Have you ever noticed bubbles (small circles) found on 2000 rupee note.
If we look carefully, the 2000 note has 9 and 11
bubbles on the front and 16 on back. These numbers indicate the launch date
of these 2000 rupee notes. i.e: 9/11/2016.
4. You must have seen the lines on 200, 500 and
2000 notes, why do you think these lines are printed on them. Let's check it
out.
It is not a shape, in fact it is for the purpose of
blind people to easily recognize the currency of the rupee note. So these
lines are raised.
There are 6-7 lines on each end of the 200 rupee note
which can be used to detect by touching.
On a 500 rupee note, 5-5 lines are formed on both ends.
For a 2000 rupee note, there are 7-8 lines on both
ends.
