    Fruit-Power Battery – Sick Science! #080

    Read the full experiment at http://www.stevespanglerscience.com/experiment/fruit-power-battery Voltaic batteries of all shapes and sizes are objects that convert chemical energy into electrical energy. You probably use batteries to power your cell phone, iPod, or any number of wireless gadgets. But did you know that you can actually use chemical energy stored within a lemon to power a small LED light? It’s true, and we’ll show you exactly how in the Fruit-Power Battery experiment.

  • Anti-Gravity Cone?!

    Anti-Gravity Cone?!

    Einstein thought it impossible: a ball rolling uphill! This new experiment shows, for the first time ever, a ball can actually defy gravity.

    The next video released will explain how the Anti-Gravity Cone actually works; what force overpowers the force of gravity?

  • The Coriolis Effect

    The Coriolis Effect

    The Coriolis effect says that anytime you’re rotating—whether it’s on a playground toy or your home planet—objects moving in straight lines will appear to curve. This bizarre phenomenon affects many things, from the paths of missiles to the formation of hurricanes.

    You may have heard that the Coriolis effect makes water in the bathtub spiral down the drain in a certain way, or that it determines the way that a toilet flushes. That’s actually wrong.

    Although, as you may have noticed while tracking a hurricane on the news, storms in the Northern Hemisphere spin counterclockwise, while those in the Southern Hemisphere spin clockwise. Why do storms spin in different directions depending on their location? And why do they spin in the first place? The answer is the Coriolis effect.

    #1. Speed of sound: Unlike light, sound needs a medium to travel through, and its speed depends on characteristics of that medium like density and temperature. In the extreme environment of a neutron star’s core, sound can travel extremely fast. But knowing that sound can’t surpass the speed of light, physicists can narrow down their models of neutron stars to include only those where “extremely fast” is less than light speed.

    This evidence seems to suggest that the dark matter is particles that are less than four times the mass of a proton and are moving at non-relativistic speeds.

    ADVANCED SCIENTIFIC NOTE: Quantum mechanics would be much more obvious if we had very sensitive eyes. If your eyes identified each photon individually, you would see them land as described in the video, and only build up to this wave pattern. The pattern that we see can be explained classically by waves, it is *ultimately* a quantum phenomenon. The only reason it’s hard to tell is because our light detectors (eyes) aren’t quite sensitive enough.

    First Light Detected from Gravitational Wave Event on This Week @NASA – October 20, 2017

    For the first time, NASA scientists have detected light tied to a gravitational-wave event. The gravitational wave – caused by an explosive merger of two neutron stars, about 130 million light-years from Earth – produced a gamma-ray burst and a rarely seen flare-up called a “kilonova”. The phenomenon was captured by our Fermi, Swift, Hubble, Chandra and Spitzer missions, along with dozens of NASA-funded ground-based observatories. Also, Trio of Station Spacewalks Completed, Fresh Findings from Cassini, and Test of SLS RS-25 Flight Engine!

    These 3 things go “faster” than the speed of light. How’s that even possible?
    Subscribe: http://www.youtube.com/channel/UCj1gf
    ↓Want more info?↓

    More about the experiment:
    Marissa Giustina’s research: http://arxiv.org/abs/1511.03190

    Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since “accelerated” to faster than the speed of light. You might go further and say that there are more distant galaxies that we can’t see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn’t from doppler and this “acceleration” of the expanding universe isn’t actually causing a true increase in velocity.

    Sometimes astronomers do say there is a faster than light “recession speed” by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that’s misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

    SCIENTIFIC NOTES:
    – Messages can also be encoded by altering the phase of the signal being sent from the antenna.
    – Phones use several (~8) frequencies at one time, and since there are limited frequencies (~100) for the tower to use, manages the sharing of them.

    LED Throwies – Sick Science! #202

    For the full experiment, click here: http://www.stevespanglerscience.com/lab/experiments/led-throwies

    Graffiti Research Lab first introduced us to the awesome throwie idea, and we loved it. Ever since, we’ve been playing around with the idea of using light-emitting diodes (LED) and throwies as a great hands-on method to teaching science. You can do it, too, and we’ll show you how!

    First Light for AMS on This Week @ NASA…

    Researchers have published the first findings of the Alpha Magnetic Spectrometer (AMS), a particle physics detector on the International Space Station that searches for various types of unusual cosmic matter. Scientists hope that by measuring cosmic rays, AMS will provide new data about the formation of the Universe, antimatter, and evidence of the mysterious dark matter believed to make up most of the Universe. Also, MATERIALS IN SPACE, OBSERVING EARTH, FARTHEST SUPERNOVA YET, BLOWING IN THE WIND, EARTH MONTH 2013 and more!

    Light Relight – Sick Science! #117

    Read the full experiment at http://www.stevespanglerscience.com/experiment/flame-light-relight
    There’s a lot of chemistry behind the simple lighting or extinguishing of a flame. Would you believe us if we told you that you could extinguish a flame just by placing it partway into a graduated cylinder? What if we told you that you could relight the fire without a match or lighter? Both propositions seem unlikely, if not downright impossible. With the Flame Light Relight experiment, however, you’ll see how a few household items can mix together and create a fire-based experience you have to see to believe.

  • Black Light Secret Message – Sick Science! #110

    Black Light Secret Message – Sick Science! #110

    Highlighters have a number of uses, from helping acknowledge important text to acting as brightly-colored markers in our favorite coloring book. Around Halloween, though, we’ve found an entirely different use for them. With the Black Light Secret Message experiment, you’ll see that certain highlighters aren’t just brightly-colored – they actually glow underneath a black light! The secret messages and floating images you’ll create with this experiment are sure to create screams of joy and shrieks of excitement.

Amazing things are possible with circuits including alarms, radios, and lights. In the Build a Light Bulb experiment, you’ll use household items to construct a complete circuit that results in a homemade light bulb.

  • Light Sticks – Cool Halloween Science

    Light Sticks – Cool Halloween Science

    Just give the plastic light stick a little “snap” and a shake and the liquid inside begins to glow. Some people call it liquid light. Our experience tells us that with light comes heat… but not this time. Light sticks are more popular than ever and have become almost required apparel for Halloween to cast an eerie glow on the candy seekers. Light sticks are also a great and inexpensive teaching tool for students to learn how temperature affects the rate of the chemical reaction.
