Blue Laser Pen astronomy pointer

5 in 1 Laser Pointer should not be confused with lamps containing light-emitting diodes (LEDs), which emit a much more diffuse beam (with much lower spatial coherence, similar to that of an incandescent lamp) and can also emit light with different colors, or white light.

Putting on a Laser Light Show for Children.Since laser pointers are available in a few different colors, these gadgets can be featured in a spectacular laser light show put on by the entire family at home. Whether one person controls multiple Blue Laser Pen
or each family member gets his or her own laser to play with, this can be a great way to create and enjoy a show together. Putting on a little music can help participants to get into the right mood, and turning off the lights is a must.
To put on a great show, space should be cleared on a light-colored wall. Both participants and spectators should stand or sit several feet away from the wall, with everyone in a single row to avoid contact with misguided lasers. As the music plays, participants can go wild making their lasers dance across the wall, interacting with other lasers. Competitive people can try staging a Red Laser Pen Pointer
fight, in which the first laser to touch the other laser wins. With a little bit of imagination, a dark room, a blank wall, and a few laser pointers can provide hours of entertainment.A green laser pointer is more dangerous than a red one because it has a higher frequency.

Have you ever seen a laser light show and wished you had one of your own?
You can construct your own mini laser light show quite simply.
1.Collect the items listed in the "Things you will need" section.
2.Take the speaker, and stretch a piece of latex over the speaker. Fasten this down with the rubber band, and make sure the latex is tight.
3.Using your adhesive, glue the small mirror (mirror side facing you) to the latex. Place the mirror in front of the speaker cone for best possible use.
4.Use some tape to hold down the button on the laser pointer to keep it turned on.
5.Aim the Laser Pointer Yellow at the small mirror you glued onto the cone of the small speaker and identify where the laser light bounces.


6.Adjust the angle of the speaker and the angle of the laser pointer until the spot of laser light ends up in the center of the wall. (you may need some items to prop the speaker and laser pointer so you do not have to hold either of them)
7.Additionally, you may have to move your speakers around so you can get the laser dot focused properly.Switch on your stereo and adjust the volume until the laser light reflecting off the mirror makes interesting patterns of light on the wall. As the speaker vibrates, the angle of the mirror changes causing the spot on the wall to move.Sit back and enjoy your laser light show.
