This demonstration talk will highlight some of the spectacular visual properties of soap films and bubbles that have remained largely unknown. Giant films and bubbles, that are not spherical, will be demonstrated. Their colours, vibrational behavior and minimization properties will be investigated. An analogue bubble computer will be constructed to solve the problem of the minimum roadway linking a number of towns. Bubbles, films and drops exist in our food and drink, in our washing up bowl, in the clouds; they are responsible for cavitation and have applications in the medical treatment of kidney stones, bubble chambers, cosmology.... a world without bubbles is 'unthinkable'!
