I read the trick candle article.

Learned Knew
 * 1) There is national candle association that studies candles and informs people the dangers of candles
 * 2) Trick candles were banned in Canada because of the candles ability to reignite if not put out properly
 * 3) Trick candles use magnesium to reignite
 * 1) The candles reignite from sparks
 * 2) The candles are not put out properly
 * 3) The candle's wicks are made of cotton

Lance, 1.) OK 2.) 5 stars.

Distillation video-

I learned that to distillation with heterogeneous mixture with a flammable mixture you should not use a naked flame. I learned that even mixed the mixture can still combust and light. You instead put the tube in water and boil the water. Then when the flammable parts are out of the mixture, then you can then use an open flame. I didn't realize that you could lit the mixture with distillation so much before everything is filtered out. This is even done with huge scales of mixtures like crude oil. The parts of the mixture are distilled out of the crude oil with the same basic way used with smaller scales.

Lance,

Right! It's called scaling up a process from lab to industrial level. 5 stars. MW

Motion dector artical-

Knew-
 * I knew some motion dectors use infrared radiation.
 * I knew that some motion detectors use photo sensors to sense light
 * I knew that some detectors dectet the warmth off of things
 * I knew that people have invented ways to avoid a motion detector
 * I knew that infrared motion detectors can tricked if you can apper to have the warmth of the room around it

Learned- Lance, OK. Well done! 5 stars. MW
 * I didnt know that certian things can block radio signals from a motion detector and not set of the detector
 * I learned that detectors have a range for the detecting you
 * I didnt know that there are three kinds of motion detectors i thought there were only two
 * I learned that a photo sensor is anything that senses light around it
 * I learned that there is a motion detector that sends out pulses and if one is blocked it goes off
