Speaking of most powerful laser pointers, I believe that everyone is no stranger. However, we often have a sudden exposure to the eyes, which will cause some damage to our eyes. But do you know how powerful the laser pen is? Next, I will tell you through six experiments.
Experiment 1: In 1 minute, the mosquito coils were burned out of white spots.
Place the laser pointer and mosquito coil on two small tables, and the two tables are separated by about 1 meter. Turn on the laser pointer and let the light shine toward the mosquito coils. After 10 seconds, it began to smell the smell of smoked mosquito coils. After 1 minute, the mosquito coils were burned out of white spots.
Experiment 2: 20 seconds, penetrating the 8-layer newspaper
The second subject is a newspaper. Overlapping the newspapers, a total of 8 layers, placed on a small table. The laser pointer is also 1 meter away and is directed at the newspaper. In just 20 seconds, the light has penetrated the newspaper to reach the back wall. The newspaper has been broken through a small hole by light.
Experiment 3: Instantly ignite the match head
Open the matchbox, the whole box is on the small table, and the laser pointer is aimed at the match head. When the light touches the head of the match, the match is ignited.
Experiment 4:burnt chicken claw epidermis 10 seconds
Chicken feet are used to simulate human skin, even though the chicken feet are thicker than human skin. Place the chicken feet on the small table, turn on the laser pointer, and align with the chicken feet. After 10 seconds, the chicken claws exude a burnt smell, accompanied by a cracking sound of oil burning. After 1 minute, the chicken skin was burned with a black spot.
Experiment 5: The sponge was cut 10 cm wide
This is the cutting ability of the experimental laser pointer. The same two small tables, the laser pointer and the sponge are separated by 1 meter. The light of the laser pen is no longer stationary, but is aimed at the sponge, moving slowly and translating about 10 cm. After turning off the laser pointer, the sponge was cut open by a laser.
Experiment 6: Black plastic bag is lit within 5 seconds
The laser pointer can be worn on the tip of the pen, and then a pattern such as a starry sky is projected on the plane. After wearing the pen, the laser is diffused and the lethality is reduced. However, in the case of a relatively close distance, the laser pointer is dangerous even if the pen is worn. Place a black plastic bag 5 cm in front of the laser pointer. After 5 seconds, the plastic bag burned up.
Please pay attention to the safe use of laser pointer
The damage of the laser pen to the eye is a kind of light damage, and the severity of the light damage cannot be ignored. The aperture of the laser is very bright and very irritating. The eyes are exposed to strong light, even if they are reflexively closed, but this is just a few seconds enough to cause irreversible damage to the delicate macular area. The laser pen needs to be taken care of by the parents. It should not be used as a child's toy. Even if it is not directly exposed to the eyes, the long-term laser will make the eyes uncomfortable and affect the vision of the child in development.
