OK, no problem.
Now some of training. Cut a short length of the glassy stick.Light up the candle again.Holding the plastic length of the stick with your tweezers like in the pic below, move it to the flame slowly.There is a point of its moving , you will notice that the ending is swelling. Move it farther trying to get the effect of a "mushroom" or ball at the ending.
Don't move the stick too close the flame because it can catch fire.
