Life few people know the word "doubt". So sometimes you will encounter a worrying situation that is not as expected. Some tips and tricks to help you through a dangerous situation are never redundant. In addition, there are also many tips to help you "predict" that future, do not miss it!

1. If a suspect is in an elevator, press the buttons for each floor

Doing this will give you an increased chance to run away or alert someone outside about someone intending to harm you.

This is also one of the tips to be used when the elevator is running "speeding". Accordingly, quickly  pressing all the buttons on the control panel will activate the emergency power supply, preventing the elevator from falling further.

2. Weather prediction with just a glass of water 

Shake any drink and pour it into a cup. If the bubbles spread to the sides, it reveals that the weather will be fine. And if the bubbles are in the center, it tells you that a storm is coming or the weather will be bleak, a lot of rain.

This is due to the effect of atmospheric pressure on the air bubbles. The high pressure dispelled the bubbles to the side. It means the weather can be sunny. When the pressure is low, the bubble will be in its original position, meaning the weather will be bleak and rainy.

3. Quench the burning pan with baking soda

When the oil in the pan gets too hot, the cook doesn't notice that the fire catches in the pan. At this time many people will think to pour water in to put out the fire, right?

But this is a taboo! Because pouring water into the oil pan will make the fire burn harder, the oil will splash everywhere.

If the fire is low, you can put some baking soda in the pan, it will absorb oxygen. However, the most effective way is to use a large cotton cloth or use a mixture of table salt, water, ammonia salt to put out the fire.

Table salt absorbs heat and isolates the fire's contact with oxygen in the air. At the same time, the ammonium salt also produces CO2, so it will put out the fire very quickly.

4. Use your phone as a reflex when you cross the street in the dark

You absolutely can use your mobile phone or camera as a light reflecting light when crossing a low-lit street in the dark. This will help drivers see you on the road and react promptly.

5. If someone uses force to restrain you from taking away, sacrifice some personal belongings on the spot

If you are on the move and you are suddenly being controlled to get away, try to "accidentally" drop as many personal belongings as possible. 

However, be sure to hold your cell phone in case there is an opportunity to call for an ambulance. And this can also help the police find you faster.

To a few people, throwing things away can distract the subject, and during their negligence you can take the opportunity to signal others to help or run away quickly.
