How do i make a light/lamp that revolves and sheds small dots of light?

BLOW A BALOON AND WRAP IT WITH WITH ROPE AND WIRE ALL AROUND SMEAR THE SURFACE WITH WHITE GLUE MADE OF PULPED PAPER (NEWS PAPER)... WHEN DRIED LIGHT A CIGARETTE AND DRILL LITTLE HOLES WITH IT. CUT A LARGER HOLE FOR THE BULB RIGHT ON THE PLACE YOU BLOWW THE BALOON. YOU CAN PAINT YOUR WORK WITH DIFFERENT COLORS.\n\nI AM AN AMEEERICAN LOL

it's usually called tube lighting

they have these black out caps for the miniature lights.  You can put them on the lights that are between the window and door.  Check Lowes or Home Depot.  You will see the string in daylight, but at night it will look perfect!

extra lighting, make it super bright

yes...but u must know the angle of incidence and angle of refraction...light up a candle and place a mirror opposite to it in a room at an angle so tat u can see the candle.then keep other mirror at a place where u can see the first mirror and the candle... continue the process till u get sufficient light. try to place mirrors in the ceiling to get better light.

Buy a large glass vase from Wal-mart (I picked one up this weekend for $1.97), a strand of 20 count lights ($.97 at Wal-Mart), and a bag of potpourrie ($1.00- I did a christmas scent, but this "craft" can be used year round, so maybe a scent/color combo that works well in thier homes?).\n\nPut the end few lights in the vase, add some potpourrie, add more lights, add more potpourrie, etc, etc, but leave the end of the cord out. I had some ribbon in my fabric bin that I used to tie a bow around the neck, and secure the cord down on the glass. When it's plugged in, as long as you have a vase with a large mouth and only slightly narrower neck (avoid the type that cinch in tight), enough air circulates that these light up air freshners are perfectly safe to use. The lights warm the potpourrie to give off scent, while looking pretty. They look nice in baskets, too.

They have clock kits that you can use to make a clock out of almost any thin item (CD, plate, metal sheet, etc.).  \n\nhttp://scientificsonline.com/search.asp?t=ss&ss=clock+kit&sid=yahoo&cm_mmc=yahoo-_-cpc-_-edmu-_-clockkits&OVRAW=clock%20kits&OVKEY=clock%20kit&OVMTC=standard&bhcd2=1142905545

The lamp consists of an illuminating bulb, and a glass bottle containing a transparent liquid, translucent wax, and a metallic wire coil. The glass bottle sits on top of the bulb, which heats its contents. The metallic wire coil is hidden in the base of the lamp, which the glass bottle is sitting on.\n\nThe wax is slightly denser than the liquid at room temperature, and slightly less dense than the liquid under marginally warmer conditions. This happens because the wax expands more than the liquid when heated.\n\nThe light bulb heats the container at the bottom, and due to heat exchange with the atmosphere, the container eventually dissipates the introduced heat. This method of heat transfer is called convection.\n\nWax at the bottom heats until it melts, and eventually becomes less dense than the liquid above it. At this time, a portion of the wax rises towards the top of the container. Near the top, away from the heat source, the wax cools, contracts, and as its density increases it begins to fall through the liquid towards the bottom of the container again. The difference in temperature between the top and bottom of the globe is only a few degrees.\n\nOne mass of wax may rise as another falls. The metal coil at the bottom helps to overcome the surface tension of the individual wax droplets, causing the descending blobs to agglomerate into a single molten wax mass at the bottom of the container. The cycle of rising and falling wax droplets continues so long as the bottom of the container remains warm and the top of the container remains cool. Operating temperatures of lava lamps vary, but are normally around 60 °C (140 °F). If too low or too high a wattage bulb is used in the base, the "lava" ceases to circulate, either remaining quiescent at the bottom (too cold) or all rising to the top (too hot).\n\nChaotic behaviour makes the movement of the wax unpredictable—hence lava lamps can aid in the generation of one-time pads for cryptographic use.\n\nThe colour of the wax and the liquid often varies and can be found in many different combinations.

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

here is a link which I hope will help. http://www.hgtv.com/hgtv/dc_lighting_other/article/0,1793,HGTV_3466_1372885,00.html \n\nyou may have to adapt the info to the flower pots you want to use.  it has clear pictures to illustrate the process.   have fun!

1) the rheostat (that little knob that increases or decreases the light coming from the light source)\n\n2) the iris diaphram (works like the iris of the eye, making bigger or smaller circles for the light to pass through)--this is usually part of the condenser

use voltage dividers with a transistorized switch.  this method lights  a number of lights matching the input voltage in this case, all the way up the tree to it, rather than just one, so note that.  (7V in gives 7 lamps on).\n\nthe first transistor comes on if the base reaches .7V (2N2222 or so will work).  the next transistor is attached to the base of the first transistor through a voltage divider, the third ....  From the collector stick in a 1V Zener for regulation (make sure you get one that withstands 12v in), and the lights then go from there straight to ground (include a resistor here to limit current, try 15 ohms to start, experiment!).\n\ndecide how many lights you want, divide your final voltage by that number, and that is the voltage per step (here, 1V).  the voltage divider then comes from the voltage per step versus the transistor base ON voltage, across a good sized resistor (say 470 ohms or 1k, whatever you want (watch the current and the power drain here).  in your case, if you use a 470 load resistor on the voltage divider, then the second leg of the divider is (470 / (1V/1V-.7V)) = 141 is about a 130 (less is more on the base!).\n\nrecap:\n\nso the voltage divider goes from the input into the 130, into both the base and the 470, the 470 goes to ground.  the emitter can tie to the input voltage, the collector goes to a 1V Zener, to a 1V lamp, a small resistor, and ground.\n\nthe other stages stack right onto this.  the input still goes to the 130, then to the base and the 470, the 470 ties to the base of the previous stage.  the emitter again goes to the input voltage, and the collector goes to a 1V Zener, a 1V lamp, and a small resistor to ground.  sorry, i can't attach a picture here.

I'm not able to give a _complete_ description...  But as far as I know, a Reuter lamp is just a laboratory light source, that uses an ordinary light bulb (along with some fancy optics) to produce a focused (or collimated) beam of light that can be used for the sort of experiments done in first year Physics lab courses.  Some have cooling fans to keep the lamp cool despite the heating from the light bulb.  Essentially, it's just a fancy flashlight on a stick.

If u meant what solution would conduct electricity then any salt solution would do  the trick. If you meant what solution would produce electricity to light a bulb then you need to prepare a dilute solution of sulphuric acid ( be careful! wear gloves! Wear goggles! If you are a kid, do it under supervision of an adult..that means your parents or teacher :-) ) In the acid solution suspend two plates of dis-similar metals ( say zinc and copper) and connect the plates to the bulb( a flash light bulb, 1.5 V) using copper wires..and see it glow.\n\nThere are other ways and more elegant styles..however this is the simplest.

flourescent ink will glow in the dark and is extremely visible during the day.  Another thing you might want to look into is "Optical Brightener"

atach a wire to each part of the batter, attach them to the light. create a circuit and you will have light
