Secular humanism is a comprehensive life stance or world view which embraces human reason, metaphysical naturalism, altruistic morality and distributive justice, and consciously rejects supernatural claims, theistic faith and religiosity, pseudoscience, and superstition.
A lava lamp is made by mixing alcohol and water and mineral oil and dyes, combining each separately. By mixing water and alcohol in the correct proportions, the mineral oil can be made to float.
Turn off the lamp and allow it to cool down before turning it back on. Once it cools, it should function properly again. A lava lamp may overheat in eight to 10 hours, depending upon the bulb and brand of lamp.
