Dynamic Dust

1) Dumas beach: This beach is located in Surat, Gujarat. It is used as a burial ground by the Hindus and till today, people claims to hear voices of people telling to each other when there seems nobody to be around you. According to locals, people who had gone there at night had disappeared in the dark. It is the reason people don’t visit this place at night.

2) Bhangarh fort: You must have heard its name. It’s a destination where a lot of people have already visited and never came back. You can visit here only at daytime as it is abandoned to visit her after sunset. According to a myth, this place was cursed by a ‘Tantrik’ and people of some villages around Bhangarh were ruined due to this curse. 

3) National Library, Kolkata: This placed appears haunting to even the guards who are cynical to do night shifts. People claims that every morning, letters and papers are found scattered on the table of the library. It’s said that ghosts of laborers who died during the construction of this library are spotted by many people. It’s also said that the footsteps of Governor’s wife is still heard at this place.

4) GP block, Meerut: This building is double storied building which is marked to be haunted. A lot of people have claimed to see four men having their drinks in their hand. This is considered to be house of evil spirits. Sometimes, a woman with red dress is also spotted to come outside this creepy place. People feel creepy while visiting this place.

5) Tunnel No. 33, Shimla: After all the scary ghosts and haunted places, read about a paranormal place where there is only one ghost who is friendly. There are numerous haunted places in Himachal Pradesh but we are going to tell you about a good one at the end. At this tunnel, people often claim to see a ghost which is believed to be a ghost of British Railway Engineer who died during the construction of this tunnel.

You can choose to navigate these places to add some more fun to your life. Even if you can’t visit here at night, you can visit these place at daytime. There are a lot more places which you could add to your navigation list but these places are destinations where the reports of paranormal activities are most!

2. p-n-p transistor (2N 557)

3. Two rain sensors ( aluminum tube of diameter 5 mm and length 6-7 cms)

4. One LED and one resistance

5. One capacitor (0.2 microfarad)

6. 3 resistors (220 kW, 100 kW, 15 kW)

7. Battery 

8. Switch

9. Wires

10. Plastic plate

Working Principle:

Two conductors (rain sensors) are placed closed together but they are not allowed to touch each other. There remains a gap between them. When water falls on the circuit, it allows the current to flow through it which sends the current to make your alarm glow or beep, either way you like. You can make an alarm which glows or beeps when it rains!

Construction:

Important thing is to join the components correctly for which I am sharing the circuit diagram in next section which will help you to make connections easily and moreover the current produced by the circuit is very minute which can only make LED to glow or could make buzzer to produce sound. Current less than 40 volts can’t be sensed by human body. It’s not dangerous at all.

Your water alarm can be activated with the help of a single water drop too!

Aluminum tubes (rain sensors) are fixed on a plastic plate with a small distance between them and water acts as a medium of connection between them and with the competition of circuit, your LED will glow.

Circuit diagram and its significance:

Circuit diagram plays a very important role. If your circuit diagram is correct, then definitely your rain alarm will work, only need is to join the components correctly and components should be in condition to work. Ruined parts could create problems.

Join circuit as shown below. At the place of LED, you can join buzzer. Buzzer will produce sound and LED will glow when it rains. Rest of the circuit and components will remain same.

I’ve always liked to join circuits. It’s quite interesting to see a circuit on paper and then further joining it with your own hands. It will produce very less current which can other lighten up LED and noting more than it. But join correct terminals and use wires which can only take lesser current. 

It’s fun to join your own circuit and make your own alarm. Especially, high school students can make it easily. It would be better if you consult your science teacher before joining it. 

Enjoy and have fun with your own Rain Alarm!

1. Facial Expressions: Facial expression says a lot about you. You can learn to detect lies by observing a person’s reaction while talking. While observing facial expressions, you need to focus on four major aspects.

• Micro-expressions: these expressions flashes on the face of a person for a fraction of second and you can figure out the lie in that one second after practicing it. Generally, a liar shows emotions of agony on his/her face.

• Nose touching/ mouth covering: It is due to the fact while lying adrenaline rushes into the nose capillaries causing itching to the nose. People who lie generally touch their nose or area near their mouth.

• Eye movements: When people are usually remembering something, their eyebrows tend to move upwards. While telling a lie, eyelids of a person blinks or people rub their eyes while lying. 

2. Way of talking: It is another method to access weather the person is true or lying. His voice and choice of words can clearly be used to depict the truthfulness.

• Voice: Person’s voice either rises or slows down while telling a lie. Tension could also cause the person to stammer. These signs can easily detect a liar.

• Exaggerated details: If somebody gives you more details than required, it is most probable that the person is lying and wants you to believe what he/she is saying.

• Impulsive emotional responses: When somebody responses at once after you complete your question, it is certain that the person has already rehearsed the question and was expecting you to question them.

• Choice of words: Generally liars ask you to question again or says the same words that you said to them before answering something. 

3. Body language: A person’s body language has much to say about them. you can see their body language changing as the sign of lying.

• Sweating: Generally people start sweating while they lie. But it can’t be termed as concrete sign as some people sweat due to nervousness or shyness.

• Nods: It happens that when a person lies, he says yes and head nods like no or vice-versa. This can be helpful in clearly watching the intensions of next person.

• Fidgeting: When people lie, their nervous energy is released in the form of fidget. Either they start to fidget with handkerchief or with something near to them.

• Throat: a person throat seems to swallow or gulp something while lying.

• Breathing: Liars tend to breathe faster. They shows a series of short breathes followed by deeper breathes. 

Although everything can’t be confirmed as certain but watching an eye over the parameters of a person can act as a tool to detect a lie!

• It is interesting to know that earth changes its polarity which means that North Pole converts into South Pole and vice-versa. This change of polarity can occur after a period of 5000 years to 5 million years.

• You have often heard about the fact that the height of astronauts grow in space. This is due to the fact that the cartilage disc in spinal cord expands like a spring causing the whole body to increase its total length and thereby astronauts become temporarily taller!

• Do you know that every year, North America and Europe moves 4 cm away from each other? It is due to the movement of continent bearing plates.

• Earth has the highest average density as compared to other planets of solar system while Saturn has the lowest. It means earth is the densest of all the planets of our solar system.

• We only see one side of the moon. We never see the other half from the earth. It is because of the fact that earth’s rotation and moon’s rotation happens exactly at same time. The other side of moon ever seen is from spacecraft!

• Jupiter acts as a life saver to Earth. It sucks all the debris from the solar system before it reaches forward. The reason for this this phenomenon is the gravitational pull of the Jupiter which allows it to create an attractive force to clean up the solar system!

• Which is the hottest planet? Your answer will be mercury. Right! But it’s not actually true. Venus is the hottest of all the planets. Mercury is however closest to sun but possess no atmosphere to hold the heat taken from the sun. On the other hand, Venus has very thick atmosphere to trap heat and thus is the hottest!

• Your one day visit to Mercury will be fifty eight days on planet earth! In actually, the same phenomenon can be experienced by visiting Antarctica where day and night are of six months!

• If it is calculated physically on mass then our solar system is made up of 99% of the sun’s mass and rest 1% accounts for the mass of planets and other asteroids!

Isn’t it peculiar to know more about our solar system? There are a lot of facts which will widen your eyes. Our solar system is unique in its existence and so as we!

Water is an essential part of our life. 70% of our body is made of water. Although, earth is also made up of 70% water and 30% land but the available fresh drinking water resources are less than 2%.

When water crises hit, it takes away many lives and create unending problems to a society. Here are the major areas which are affected by water scarcity:

• Health: In many countries, due to water scarcity, people are forced to drink contaminated water. This water affects their health. When contaminated water enter their body, it creates a lot of diseases. Moreover water scarcity leads to poor sanitation facilities which create risk to the lives of people. People have to use stagnant water in which water born disease like malaria starts its life. Hence, it becomes a dangerous game for the people.

• Hunger: Water is one resource which is a necessity of every living being. Either it is a plant, animal or human being. When scarcity of water arises, it becomes difficult to provide plants with necessary water. 70% of world’s water is used for agriculture and its crises leads to decrease in crop production. In most areas, agriculture is dependent on rains which are probable. This adds more weightage to world hunger crises.

• Education: Education doesn’t seem directly linked to water scarcity but in actual, it is related to it. In many parts of the world where people are hit by water scarcity, children especially girls are abandoned to go to school to serve family by bringing water from farthermost areas. If they go to school, then they have to work at their homes too which makes them tired and decreases their efficiency of studying.

• Poverty: As water is not accessible to many people. It decreases their standard of living. It becomes difficult for people to arrive at their work place on time. If people have to worry about the very basic necessity of their life ‘water’ do they would be able to contribute their 100% at work?

Water scarcity is a problem which has a huge impact on key areas of life as it is linked to basic needs of every life form. Without it, we can’t even think of survival. Water is a precious resource and it’s our duty not to waste it. Today, we have access to it. It’s not certain that we’ll have the same access tomorrow. Situation can change with time. We need to respect it and should make wise use out of it!
