 Steps

    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 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.
    8
    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.
    9
    Sit back and enjoy your laser light show.

Edit Tips

    The louder the music, the larger the light show.
    Use a fog machine (if your laser is strong enough to shine through, like a green laser) to enhance your experience. Strobe lights are fun to use here as well.
    The greater the distance between the mirror on the speaker and the wall will create a larger pattern.
    It might be a good idea to have on hand some spare batteries for your laser pointer.

 Warnings

    Do not look directly into laser beam with your eyes. Laser pointers cause pain before they cause eye damage due to the low power restrictions but it is never a good idea to look directly at the laser beam or shine it into any one else's eye)
    Do not shine your laser into cars or planes. This could cause the driver to become temporarily blinded; and they may lose control of the vehicle that they are driving.
