Candles are a stick of wax with a wik (the stick thing at the top) at the top of it and they are used to make a flame.
The causes to make the flame are solid wax, a wik, the matches and oxygen. These four things make the flame.
After that the effects are made. The effects are smoke, heat, liquid wax and the liquid wax getting soaked up the wik.
Flames need fuel to keep them going so the flame melts the solid wax and it turns into liquid wax. Then the wik soaks up the liquid wax like a tissue soaks up water. Then the liquid wax makes his way to the top of the wik wich is where the flame is, and the flame feeds on the wax to keep it going.
Candles are really useful tools but they can also be dangerous so be careful around them.
