In addition to figuring out who did it, police have to figure out how they did it. And to do that, they often use a technique called blood spatter (not “splatter”) analysis.
Our eyes see everything going on around us. The eyes send this information to our brain, which interprets the information it is given. Sometimes the brain has to fudge a little when making these interpretations. This is especially true when our eyes see something that the brain knows cannot be true. In cases like this, the…
We all know parents have eyes in the back of their heads. They always know what you’ve done, where you did it, and sometimes even why you did it. We’ll never fully understand how they do this; even science cannot explain this natural phenomenon. But this experiment can at least put you on somewhat equal…
Light traveling in a straight line appears colorless. But there’s more to light than just colorless nothingness. When light passes through a wedge-shaped piece of glass called a prism, the light is separated into 7 different and unique colors. You see these colors when light passes through rain or moisture producing a rainbow.
Believe it or not, scientists are still arguing precisely about what scientific principle should be used to explain why an airplane can fly. One explanation, the Bernoulli Effect, is commonly used to describe the phenomenon of flight. In this experiment, we demonstrate the second explanation – the Coanda Effect.
Gyroscopic inertia – a strange, complicated word – is a force common all around us. It explains how we are able to ride a bike, how planes navigate, and how a figure skater is able to do those lightning fast spins. Here’s a simple experiment that’ll clear up this confusing concept. Note: the hardest part…
Ever wonder why igloos are dome shaped and not square? Ever been amazed at how a suspension bridge can hold the weight of hundreds of passing cars with little or no apparent support underneath it? This experiment demonstrates how arches are used in architecture not only for aesthetic appeal but for a very useful and…
