Before heating is solid

After heating is liquid

2 - Candle

Before heating is solid

After heating is liquid

When Candle is heated it melts and liquid form of wax falls off which again becomes solid in second after reaching the floor. The melting point of candle is 130 degree Fahrenheit or above.
