Four white cylinder of the same height, put on each other. Formed a "candle". Light it from the top (Fig. 1). Then, starting from the top, eliminate the cylinders in side - by-one. When you fly off the top, the candle will continue to burn, but on the cylinder below. Falls next, as the candle continues to burn.
What's the secret? All wooden cylinders have a narrow vertical slit on one side. It comes exactly to the center (Fig. 2). When the cylinders are formed, the slot must be on the same line, on the opposite side from sitelab the centre of the upper cylinder inserted "secret" wick. It is made of thin wire and the size is a bit longer Sanogo of the cylinder.
The top of the wick has a small round plate, which prevents the wick to fall down (Fig. 3). At the tip of the wick wound a piece of cotton soaked in kerosene.
When after hitting a finger to the side will pop out of the upper cylinder, the wick below, will take the next cylinder. And the candle will continue to burn.
