Have you ever tried to pointed out constellations with friends? Both your friends and you try to locate the stars you're looking at. See, there is the moon over there. Now one thing named Laser Pointer (laser range: 3 km), we have a chance to play with it. We can point out into the place far away from us, pressing the button, and light streches from your hand to infinity. It only takes one 16340 battery.
How to use: Just push the button, and then you can see striking green starry light shoot forth. The light can point at any targets, such as photos, blackboard, video monitors, and so on.
How To Burning Matches: 1. Please put the laser in a dark place, and adjust the laser to the biggest spot, then you can see the light beam clearly 2. After you see the beam, please put the match in the tiny and shiny place, that means the best combustion position which is the focusing pointer 3. Only if you put the match at the right position, it can burn
Note: Never point at people and always avoid direct eye contact. Please keep out of reach from children, pets, and so on.
