Secrets of 8 uses of laser pointers
People familiar with blue laser pointers generally have two different attitudes towards laser gadgets. First of all, it does not require a laser pointer, which is dangerous to the human eye. Laser enthusiasts with a second opinion think that laser pointers are of great help to us, but they are indeed a right-hand man in our daily lives. Personally, laser pointers can hurt your eyes, but I think they are still necessary tools for stargazing and long-term presentations.

1. Light painting. Have you heard of light painting? This is actually impressive. Light painting is a type of photography that combines long exposures with handheld or natural light sources to create stunning and beautiful landscapes. Although this sounds like a new phenomenon or trend, we assure you that it is not.
2. Make a fire. Hand-held high-power high powered laser can burn, blast balloons, light matches and light fires (as long as you have lighter liquids or gasoline). If you are an avid outdoor enthusiast (or female), like camping, or think of yourself as a "prepare", then a handheld laser machine is a good tool to carry with you (this pun may be intentional).
3. Camping. Therefore, since you know that lasers can send out distress signals well, they have many other uses in campgrounds. Have you forgotten to strike any game anywhere? No problem, if you have a high-power handheld laser on hand, you can simply collect some lighter liquids, ignite and dry leaves, and hit them with the laser-you will soon catch fire! Although this is not the most effective way to start a fire, it is absolutely effective as long as you have gasoline or lighter fluid on hand. 3. The spread of birds. What is the beast? Yes, it is one thing to remove birds from unwanted places with a laser; in fact, it is a profession. Have you seen multiple birds in a crowded shopping mall or airport? Maybe you have seen a flock of birds sitting on wires? There are professionals who are responsible for safely removing birds from these areas. In most cases, lasers are the most effective and efficient method.
