A dislocated shoulder results when the head of the humerus pops out of the socket joint. This is not a gradual event, but rather a sudden even where the shoulder moves out of its normal location. Learn how to treat a dislocated shoulder and stay fit in this sports medicine how to video.
The picture may look like a mushroom cloud, but it is actually a can filled with hydrogen exploding. The can is fired into the ceiling. This demonstration still needs a little improvement in the area of safety (but it looks really cool). The problem is the partial pressure of hydrogen drops as the gas escapes and is replaced with air. This causes the reaction to be an explosion instead of a flame. Hydrogen is a tempermental element like that.
Before the internet, acquiring enough data to analyze was challenging. Now we have the opposite problem: a deluge of data makes trying to sort through it nearly impossible. That's where data science comes in.
On this video I will demonstrate a simple concept of stack base overflows. This is the first part of my exploit development tutorials and after that I will demonstrate seh buffer overflow, ROP/DEP/ASLR, spraying the heap, search for bugs/think different etc.
Fireworks are synonymous with holidays like Fourth of July and New Year's, but rarely do you ever hear about fireworks or explosives going off during a Christmas celebration—until now.
Nikola Tesla is one of the most tragic figures in the history of science, a history that is practically filled to the brim with tragic figures. Francis Bacon, a 16th century philosopher and scientist, caught pneumonia and died because he was trying to stuff snow into a dead chicken. Marie Curie died as a result of her long-term exposure to radioactivity, and her papers from the 1890s are too radioactive to touch without protective gear to this day.
Place the neodymium magnets on the track and place four or five ball bearings in a line touching one side of the magnets. When you are ready to fire it, nudge the single ball bearing so it slowing rolls toward the magnets.

Attention aspiring scientists and chemists! Learning to balance equations and finding it to be a bit rough? This video is here to help. Learn the basics of chemistry with help from this video on how to balance equations with C (Carbon), H (Hydrogen), and O2 (Oxygen).
The Winogradsky column, invented by Sergei Winogradsky, is a device for culturing a large diversity of microorganisms. Pond mud and water are mixed into a column using carbon sources like newspapers and sulfur sources like egg yolks. Left in the sun for a few months, the column becomes a colony rich with microorganisms, bacteria, cyanobacteria, and algae. In this video, scientist Karen Dodson shows you how to make your own.
No, colorful electrolysis has got nothing to do with zapping the hair off of a punk rocker's head. Electrolysis of water, according to Wikipedia, is "the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water." In this video, you'll watch in amazement as a young scientist colorful electrolysis to transform ordinary water into a psychedelic display.
Caroline and Val from New Scientist make plastic from milk and vinegar. Sure it likes like food at first, but leave it for a couple days, and it will be plastic. Just try it for yourself.
Scientists of the University of Twente in the Netherlands won a prestigious place in the 'Hall of Fame' of videos about fluid-in-motion. They have made a video of leaping shampoo, in which they explain the so-called Kaye effect. Scientifically interesting, but also of great aesthetic beauty! Get out your shampoo and try it yourself.

My Fat Rocket Hairstyling ideas demonstrates this party hairstyle for long hair. Divide the hair into a few section before beginning. Pull a curling iron through the hair strand in a downward twisting motion. Move the curler through the hair slowly so the hair curls up at the ends. Using the right motion, a hair straightener can also be used to create the curls. Some strands of hair may need to be processed more than once. Use hairspray to secure the look. For a more sophisticated look, after...
Paper plane designed by Joost Langeveld. This one is not very difficult to fold and flies like a rocket. Just a little glue needed.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
This tutorial shows how to make a very simple rocket using 3D Studio Max.
In a previous video by NurdRage, he showed you how to make manganese sulfate ("How to make MnSO4 from MNO2 (two separate ways)"), but there can be situations where the iron in the precursor would carry over and contaminate the product. Recrystallization doesn't work for this high level of contamination, so a different approach is needed.
