Begin in an environment with a steady light source (such as in natural light in front of a window or in a room with an incandescent lightbulb).

If you are using an electric beater, be sure there is an outlet nearby for both light conditions-even if you have to change rooms.

Set your computer screen with a solid, light-colored background, such as the blank, white screen of a document program. Place a chair in front of the computer and adjust the height so that the computer screen is at eye level when you sit on the chair (or if standing is easier, that is fine, too).

If you are using a computer as your light source, place your computer on a sturdy table or counter.

(Have an adult help if any lightbulbs need to be changed or lamps moved.)

If you are using a CFL or LED light source, make sure that you have a room where the CFL or LED lightbulb can be the only source of light, such as a closet or a room at night.

Chair that will allow you to sit eye-level with the screen (optional).

High table or counter if you use a computer as a light source.

Compact fluorescent lightbulbs, or CFLs, and LED lights also work as well.) MacBooks and many other recent computers do not work well, however, because they do not have flashing screens.

Rapidly flickering light source (Many computer screens have flashing screens and work well.

Steady light source such as light from a window or an incandescent lightbulb.

Use an adult's help with any electrical appliances.) A beater with four blades works best for this activity.

Eggbeater (A hand-rotary beater is preferred, but a handheld electric beater works as well.

In this activity you will use a rapidly flickering light to create some interesting optical illusions. Our visual perceptions can differ from what is really there. But this also makes the brain vulnerable to being tricked. It is especially good at noticing patterns, even when information is missing. Our visual system has evolved to serve us well. Others specialize in recognizing the details of what we see. These tend to work fast, at the expense of detail. Some are specialized to recognize movement and location as well as the rough outline or shape of what we see. Rods are sensitive to movement, shape and intensity changes they are very sensitive to light.īrain cells involved in processing visual information also have their own special jobs. Cones are sensitive to color and suited for detail they need bright light. They send electrical signals to the brain when triggered.

It is equipped with two types of light-sensitive cells: cones and rods. The area at the back of our eyes is called the retina. Our eyes register incoming light electrical pulses transport the information to the brain, which processes it and informs us of what we see. We see with our eyes, but also with our brains. Try this activity, and you will find out how! Our brains are quite clever in helping us interact with the world, but they can be fooled. Scientists now know that what we perceive can be very different from what is really there. Be sure to check with your local jurisdiction to ensure legal usage of your beacon light.Do you have to see it to believe it? You might want to rethink your strategy. There are very few usage limits for flashing white LED beacons, if any, depending on restrictions within your area.

White beacons are mainly used by school buses white beacons make other drivers aware of the school bus being present, especially in difficult weather conditions, so that vehicles approach with caution in case kids are crossing the road.Please check with your township/city laws to ensure legal use of this product before purchasing. Blue beacon lights are usually associated with police vehicles and may only be legal for law enforcement to use.For more information on why green beacons are used, read this blog. Green beacons are mostly used for snow plow trucks, salt trucks, and other safety related vehicles.Flashing red beacons should be used for emergency vehicles such as police, EMTs, and firefighters.

Having a red beacon will imply that vehicles around you should move out of your way and stop. Red beacon lights are commonly used by emergency vehicles, as red indicates danger and urgency.Flashing amber beacon lights are commonly used by overloaded vehicles, agricultural equipment, road construction vehicles, mining equipment, and mail carriers. Caution may be needed because of difficult visibility because of weather conditions, road obstacles, slow traffic, or potential hazards. The yellow/amber color indicates that caution should be shown by vehicles passing by. Amber beacon lights are used for a variety of applications.
