Candle swing - physics experiment

http://www.fizik.si Cut off an ordinary candle on both sides so that you get to the wick. Stick a heated knitting needle in the middle of the length. Put the candle horizontal and put ends of a needle which stretch out of the candle on two glasses. When we light up both wicks, the candle starts to swing. When a drop of wax falls down on one side, the candle looses its balance and preponderates to the other side. There the flame grazes the candle, so that a drop of wax falls down also on this side. Candle looses its balance again and preponderates back again. So the candle swings until it runs short. This is physics experiment for science project. http://www.fizik.si Navadno svečo na obeh koncih odrežemo, da pridemo do stenja. V razpolovišču dolžine zabodemo v svečo segreto pletilko. Svečo položimo v vodoravno lego, konca pletilke, ki molita iz sveče, naslonimo na dva kozarca. Ko prižgemo oba stenja, sveča postane gugalnica. Ko na eni strani pade kapljica voska, sveča izgubi ravnotežje in se prevesi na drugo stran. Tam plamen zaradi nagnjenosti sveče bolj oplazi svečo, tako da tudi na drugi strani pade kapljica voska. Sveča spet izgubi ravnotežje in se prevesi na prvo stran. Tako se sveča guga in guga, dokler je ne zmanjka.
