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.
Give the lamp time to warm up. Some lava lamps take a couple hours to warm up enough to start floating, but this homemade oil version usually starts moving in less time than that. Wrap your hand in a cloth and touch the jar every 15 minutes. It should get quite warm, but not searing hot.
