  1. DIY Magnetic Rocket Experiment

    DIY Magnetic Rocket Experiment
    Launching a rocket into space is expensive. The current chemical method requires over 800,000 gallons of liquid propellants. On average it costs $450 million per shuttle launch, which is in addition to the cost of the shuttle itself. The Space Shuttle Endeavor cost $1.7 billion. So, as costs continue to rise some scientists and engineers are trying to come up with an alternative launch method. Continue reading →
  2. Magnetic Liquid Body Armor

    Magnetic Liquid Body Armor
    The popular Iron Man movie franchise and comic features a suit of body armor that could make any engineer green with envy. The Iron Man suit, a work of science fiction, seems to be a feat of futuristic engineering not yet possible today. Or is it? Scientists are working on an impenetrable suit of body armor consisting of iron particles and a carrier liquid. This liquid body armor is possible because it contains magnetorheological (MR) fluids.

  3. How To Use Magnets For Geocaching

    How To Use Magnets For Geocaching
    The modern version of treasure hunting doesn’t involve chests filled with gold or cloth maps marked with an X. Instead of searching for hidden treasure buried beneath the sand, you can find a network of different objects and containers carefully disguised all over the world and recorded as geocaches. Geocaching is a treasure hunting game where you can hide objects with varying degrees of value in interesting places. Then, other geocachers have to follow your clues and hints in order to locate the hidden treasure. Continue reading →

  6. How Does Magnetic Putty Work?

    How Does Magnetic Putty Work?
    If you think regular silly putty is a gooey ball of fun, you will love magnetic putty. Magnetic putty becomes magnetic when iron oxide particles are added to silly putty. The iron oxides magnetize the putty making it a million times more fun and entertaining than regular putty. When magnets are within range of the influence of its magnetic field, the putty will slowly swallow them. Because the magnetic field of the putty is strongest at the center of the blob, the magnets are engulfed. The putty slowly sucks magnets in until they reach the strongest point of the magnetic field.

  8. Dead Stars and Magnetic Fields

    Dead Stars and Magnetic Fields
    When you look up at a night sky, how many of the stars you see are dead? The answer might surprise you but don’t let the thought depress you - dead stars are fascinating! A star’s death may progress in one of several ways such as becoming a neuron star or even a magnetar, one of the most powerful magnets in the universe. A more common death for a star, however, results in a white dwarf. White dwarf is believed to be the last stage in a star’s life-cycle and even in this final stage, white dwarf stars can have curiously strong magnetic fields. Continue reading →

  10. The Magnetic Sensor of a Tiny Worm

    The Magnetic Sensor of a Tiny Worm
    Many animals navigate using the Earth’s magnetic field as though they have their own personal compasses. Birds, for example, can use the Earth’s magnetic poles to navigate during migration. Even monarch butterflies are able to use magnetic field lines although it’s more of a secondary navigation method for them. While scientists have already observed the symptoms of an internal compass in some animals, they have never pinpointed the exact part providing these navigation abilities until now.
