Why is ketchup so hard to pour?
AdultsFoodPhysicsScienceEver go to pour ketchup on your fries...and nothing comes out? Or the opposite happens, and your plate is suddenly swimming in a sea of red? George Zaidan describes the physics behind this frustrating phenomenon, explaining how ketchup and other non-Newtonian fluids can suddenly transition from solid to liquid and back again.
Anti-Gravity Wheel Explained
AdultsPhysicsScienceEngineering...It's a little shaky but if you average out the oscillations I think the result is clear. Again, huge thank you's to A/Prof Emeritus Rod Cross, Helen Georgiou, Alex Yeung, and Chris Stewart, the University of Sydney Mechanical Engineering shop, Duncan and co. Ralph and the School of Physics.
Anti-Gravity Wheel?
AdultsInternet CulturePhysicsExperiments...In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt like.
When Water Flows Uphill
AdultsPhysicsScienceCooking...In the Leidenfrost Effect, a water droplet will float on a layer of its own vapor if heated to certain temperature. This common cooking phenomenon takes center stage in a series of playful experiments by physicists at the University of Bath, who discovered new and fun means to manipulate the movement of water.
Amazing Water & Sound Experiment
AdultsPhysicsScienceExperiments...The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye.
These Japanese Scientists Discovered A Way To Levitate Objects Using Sound
AdultsScienceTechnologyPhysics...Droplets, pellets, a stick of wood, nuts, screws, diodes, if the object in question is small enough, than this machine can not only lift them into the air and hold it in place, but move them around on all three axes
This 'Balance Artist' Can Balance Anything
AdultsArtCreativityPhysics...His name is Rocky Byun. The video was shot at the Dubai Mall.
Incredible Chemical Reaction!
AdultsPhysicsScienceChemistry...This is a classic chemical reaction. It's called the iodine clock reaction. There are several variations of how this chemical reaction can be performed using different chemicals than the ones I used in the video. You can order clock reaction kits from several science related websites. You can also use simple store bought chemicals like vitamin C, iodine, hydrogen peroxide and starch. A quick internet search will turn up multiple ways of performing the experiment.
World's Roundest Object
AdultsPhysicsScienceProblem-SolvingThe world's roundest object helps solve the longest running problem in measurement -- how to define the kilogram.
Amazing Resonance Experiment!
AdultsCreativityPhysicsExperiments...So this experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First add sand to the plate then begin playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand "falls" into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.
How Liquipel Will Make Your Phone Waterproof
AdultsPhysicsTechnologyGadgets...We check in with the team at Liquipel, a company that impressed us last year with its water-resistent nano-coating for smartphones. Dunking an iPhone into a tub of water and watching it still work perfectly is still amazing and something our brains struggle to comprehend.
Mystery of Prince Rupert's Drop at 130,000 fps - Smarter Every Day
AdultsPhysicsScienceTechnologyBeing able to calculate the failure front velocity of a Prince Rupert's drop is a pretty big deal. For years this was a scientific mystery. High speed camera technology is only recently fast enough to provide data like this. Thanks to Vision Research for letting me use the V1610 to try to unravel this mystery for the public in general.
