But what if you could a make a giant bubble over 1 meter (3 ft) tall? Once you know the secret behind these super bubbles, you can amaze your audience by surrounding them in a human-sized bubble!

Scientific Tuesdays: Amazing Magnet Motor

Classical mechanics is good only up to a certain point, then you need quantum mechanics when you get down to a lower scale. For example, classical mechanics says that kinetic energy is 1/2mv^2 where as when you reach the speed of light, KE=mc^2. It's not because you found a cheaper way to break a bound that you'll end up with more energy than the system has to offer. [endtext]

The ferromagnetic nano-particles are coated with a surfactant to prevent their agglomeration (due to van der Waals and magnetic forces). Although the name may suggest otherwise, ferrofluids do not display ferromagnetism, since they do not retain magnetisation in the absence of an externally applied field. In fact, ferrofluids display paramagnetism, and are often referred as being "superparamagnetic" due to their large magnetic susceptibility. True ferromagnetic fluids are difficult to create at present. [endtext]
