Exposure to vacuum does not cause the body to explode, or blood to boil. You will not freeze and you will not instantly lose consciousness. You will not explode either. There is a correct belief that the pressure inside your body pushes against the weight of the air pressing against your skin. To balance this weight of air, each square meter of our body pushes back with 10 tons. The total weight of air tall person bears on their skin is about 20 tons. But this doesn’t mean the internal pressure of the body’s tissues will make it explode. Skin is quite tough and it would not simply tear. The body would expand to nearly twice its usual volume because the water in your tissues would turn into steam. Don’t hold your breath. Holding your breath is likely to damage your lungs, something scuba divers have to watch out...
I’m a scientist. I’m a physicist, that makes me a scientist. What is a scientist? Well… scientist are people who are always wondering why. Scientist are like two year old kids. I like to call ourselves ‘the why people’. why is the sky blue? why is the sea blue? why is this slice of pizza I forgot 2 weeks ago behind my bed blue? A scientist makes him or herself debate all kinds of weird questions: Who eat bees? How come penguins’ feet do not freeze? Sometimes questions are disturbing How fat must be a man so when shooting him with a bullet it won’t cross his entire body? Well, at this point, you will agree with me that if you do the math you are definitely a psychopath. I did it. It’s 650 kg. Why do cats always land...
In this experiment we tested UHU glue against rivets. We assembled several sheets of aluminum to get a panel using both methods and we test them in a dynamic load test. In conclusion of our test we discovered that the UHU glue can withstand several times the number strikes the rivets can providing a durable bonding. We also design A pyramid of tennis balls hidden in a cube of them to announce UHU was about to build the highest tennis balls pyramid...
Hands-on science for all: Bayer is sending its interactive exhibition “Science For A Better Life” on a world tour. Bayer’s mission is the theme of the exhibition, which gives visitors a chance to see and experience for themselves how Bayer improves the quality of life for people worldwide. The exhibition focuses on the topics of health care, agriculture and high-tech polymer materials. I had the opportunity of being the guide for groups during the days the exhibition was in Madrid. The letters on the exhibit boxes combine to spell out Bayer’s mission, “Science For a Better Life” The exhibits comprise 21 approximately two-meter high boxes with capital letters, each of which refers to a Bayer topic, from A for Aspirin via E for Energy-efficient Mobility through to R for Rice. Each box contains images and informational text on...
The effect that you are seeing can’t be seen with the naked eye. The effect only works through the camera. Set up your camera and switch it to 24 fps. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it’s moving backward set the frequency to 23hz. If you want to look like it’s moving forward in slow motion set it to...
The reaction between baking soda and vinegar generates carbon dioxide gas which extinguish fire. Catalytic decomposition of hydrogen peroxide by potassium iodide generates oxygen which ignites the stick again....
Mag Surf is a demonstration of superconductor magnetic levitation we were able to perform in the show thanks to the University of Paris Diderot. The skateboard, rides on a magnetic track. Super-cold liquid nitrogen blocks the magnetism of the magnetic field in the track in its way trough the superconductors in the board. The effect is a very cool flying skate....
As you dip the Square Bubble Maker into the solution, the solution is stretched between the struts and the soap film clings to the sides of the structure, causing the bubbles to appear square or cubic. The soap film uses the shortest distance possible while still connecting all sides. We also trained a lot to get a tornado inside a soap bubble. Check how we did...
Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and low thermal conductivity. Aerogel is a superhydrophobic solid. In chemistry, hydrophobicity is the physical property of a molecule that is seemingly repelled from a mass of water When a surface is covered by aerogel powder that surface becomes extremely difficult to wet or get dirty. Aerogels made with aluminium oxide are known as alumina aerogels. Alumina aerogels are being considered by NASA for capturing hypervelocity particles. Antena 3...
Thanks to the Leidenfrost Effect water dropped on an extremely hot surface is capable of floating instead of immediately evaporating. While studying the effect, physicists at the University of Bath realized that not only does the water float, but under the right conditions and temperatures it can actually climb upward. The playful experiments lead to the creation of an incredible superheated maze. Thanks to Alessandro Narduzzo we could perform this amazing demonstration on the show....
