Physical change.

Only the melting is physical (can easily be reversed by cooling down) but the actual burning (flame) is a complicated chemical set of reactions.
As we move down the group, the melting point decreases.
Melting Point
Salt doesnt slow down the melting of ice. It actually speeds up the melting in most cases because the addition of salt lowers the temperature required for the water to freeze. That's why they will often put salt on the roads after a snow storm...to melt the ice.

Use old candle wax , melt it down pour into glass container and let harden. Or you can try melting old newspaers with candle wax for a unique creation.
Aunt Sally believed that "witches' dough" was oozing down Huck's head when she saw the candle wax dripping on him.
closer it is to base down the slower it melts, closer it is to base up the faster it melts.
There are many things that physically chance when a candle burns. The wick burns, and turns into ash, and wax of the candle melts and runs down the sides of the candle or container.
An ice cube melting, a candle burning down, and a balloon deflating are examples of things that get smaller as time passes.
Only the melting is physical (can easily be reversed by cooling down) but the actual burning (flame) is a complicated chemical set of reactions.
A candle wick is a thin string down the centre of the candle.
gravity
It sure does and trickles down the candle
a beat down
it goes down
