The beam from green laser pointers is strong and can be followed a great distance from its source. Green laser pointers can be used for presenting information to audience, watching birds or by tour guides and construction engineers pointing to something that holds interest. Carrying out experiments with green laser pointers is both educational and fun. Below are some of the wonderful experiments you can perform with green laser pointers but consider safety. You can bust balloons with green laser pointers with about 75Mw in the dark. Note that black or dark colored balloons will the best to work with in this experiment because they take in the green light faster. The bright colors will have too much reflection and more energy will be needed to pop the balloon. You can use green laser pointers to move objects such as the wings in a mill. You need a mill having an absolute vacuum on the earth and have support wings with almost no friction. Target the laser beam to the wing and it will start to move very quickly. You can also split green laser pointers beams with the laser by use of slide. You can also use them for diffraction grating. Although working with green laser pointers is fun and very adventurous, you must be careful about safety. It is advisable especially with the high powered lasers that you never shine the light directly to a person, an automobile or an air craft. You should also use the green laser pointer in a controlled environment; do not light the beam continuously for thirty minutes in normal temperatures. During cleaning green laser pointers, make sure that you remove all the batteries and leave the cap open as a precaution. Use an old toothbrush to remove debris on the lens and dampen a cloth with alcohol and then use it to clean the device. Blowing the lens is not advisable. The other thing to note is that even though the laser beams can bring fun to your life they are also dangerous when mishandled. Take care of your hands when handling the device and read the users manual before you operate the it to know where the devise poses danger and where it does not.
