Three Answers to Know | General Science

1. What are Green Crackers?

Air pollution by crackers has been increased last year to control cracking of crackers.  This has saddened fireworks enthusiasts and fireworks makers.  Therefore, an attempt was made to reduce the eco-fire.  These green crackers are designed to reduce pollution by 20 to 30 percent more than conventional crackers.  The light and sound available in regular crackers are also available in these green crackers.  The prices are also lower.  Although these green crackers are not fully marketed, fireworks enthusiasts can buy them wherever available.

2. Getting sick in the rain makes you sick.  But why not have a physical problem with bathing everyday?

Most people think that getting wet in the rain can affect their health.  But that's not really the point.  Cold weather can affect people with low immunity.  Bacteria and viruses are released when rainwater falls into the ground.  It is for such reasons that the possibility of physical condition emerges.  Otherwise, those who are highly immunized will not be affected by rain

3. Why are school vehicles yellow and ambulance white?

Yellow has 1.24 times more attractiveness than other colors.  This will cause the yellow vehicle to be visible to the far side.  It can also be seen in rain and snow conditions.  Other vehicles can also help you to be careful since it is a children's school vehicle.  School vehicles are yellow because they can prevent accidents.  White color is easily visible next to the yellow.  Visible even in low light.  In medicine, white is also seen as a symbol of purity.  So the ambulance carrying the patients shows up in white.
