Common red laser pointer

Most demo laser Pointers are red, but green ones are easier to see, so it's good for both the presenter and the person listening. However, red light is bad for your eyes because it gets tired easily. If you use green ones, they are friendly to your eyes and don't stress your eyes, so you don't get tired easily. You can make a good presentation because it's stress-free. It is easy for the listener to see and therefore leave an impression. After that, try moving the light closer or away from it, slowly or quickly to attract the cat's interest. The cat follows the movement with its eyes, sometimes trying to catch it. Healthy cats chase light and start running. When I caught up with him and tried to catch up with him I turned off the light and I was surprised to find him around and cute too. One thing to remember when pointing with a high powered laser is that you are always standing on the right side of the slide. The material is generally written from left to right, so if you stand on the left and speak with a pointer or finger to the material, the character will be hidden in the speaker's body. Because it becomes. BTW, the fire from the muzzle of this machine gun is really blue, and it does double duty as a cigarette lighter. It seems to develop into the rather dangerous act of suddenly pointing a machine gun at an approaching opponent and saying I should borrow the ignition. As with hard metal flame nunchucks, use with care.
