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.
And so began my research into how to de-cloud a cloudy lava lamp. Mathmos, the makers of the lamp, insisted that nothing could be done but were happy to supply a new filled bottle for Â£23. Not too bad if you've only got one but it would soon add up with the number I was trying to fix.
