25 Mind Boggling Facts About Our World
Adults ScienceDid you know that in all of history men have only mined two Olympic sized swimming pools worth of gold? Or that frogs use their eyeballs to swallow? If you did...congratulations, you're pretty smart. If not, read on because these 25 mind boggling facts about our world will probably change the way you see some things.
Incredible Chemical Reaction!
Adults ScienceThis 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.
How do they do artificial diamonds?
Adults ScienceGemesis diamonds are mostly yellow due to the Nitrogen in the atmosphere getting inside the crystal during the growing process. Apollo diamonds can be created in all colors including colorless depending on how much impurity is introduced in the growing chamber. e.g. add boron to make blue diamonds.
What is fat? - George Zaidan
Adults ScienceAs the narrative goes, fat is bad. Well, it's actually more nuanced than that. The type of fat you eat is more impactful on your health than the quantity. George Zaidan examines triglycerides, the varied molecules that make up fat, and how to identify which types of fat you are consuming.
Mystery of Prince Rupert's Drop at 130,000 fps - Smarter Every Day
Adults ScienceBeing 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.
Chicken Head Tracking - Smarter Every Day
Adults ScienceChickens have a great ability to keep their heads stable. Our bodies use a gyro-like mechanism in our ears which has 3 mutually orthogonal inertial measurement devices. Modern motion processors use something called an Inertial Measurment Unit (IMU). These devices provide movement data which can be used to compensate for the movement. Chickens apparently have the same type mechanism only with a higher update rate.
