uhf microwave gun
Bookmarked 506 weeks ago
there is always a powerful and dangerous uhf weapon the power of the microwaves that are in microwave ovens has been weighing on my mind for a long time its magnetron uhf generator radiates electromagnetic waves of 800 watts uhf energy 2450 mhz frequency just try to imagine one microwave oven can produces as much radiation as 10 000 wi-fi routers 5000 cell phones or 30 cell phone towers can do in order to prevent this power from breaking out of microwave ovens there are steel double protection shields in microwaves i want to warn you that uhf radiation can harm your health microwave ovens high voltage can be deadly but it wont stop me i want to point out that uhf radiation affects appliances much more than humans and animals even when appliances were 10 metres away from a magnetron it began to break them down tv and mini center were making strange roaring sounds our cell phone was losing connection and finally it malfunctioned the magnetron affected wi-fi routers most of all when i

col john stapp takes a lot of g039s
Bookmarked 623 weeks ago
air force flight surgeon john paul stapp subjected himself to a number of extreme experiments in the late 1940039s and early 1950039s in order to acquire data on the human body039s ability to withstand extreme forces including rapid deceleration exposure to high speed winds and other hazards associated with jet aircrafthis most dramatic and dangerous tests involved the use of a rocket sled which accelerated stapp to just bellow the speed of sound before decelerating back to a standstill in a fraction of a second subjecting stapp to enormous g-forces the forward facing configuration known as quoteyeballs outquot presents the very real danger of cardiac damage which could even be fatal although stapp was restrained by a specialized harness this could not completely eliminate the cardiac dangeranother very real hazard of such rapid deceleration is retinal detachment which can cause permanent blindness in one of stapp039s deceleration experiments he was left unable to see after the deceleration stapp feared that he would be left blind by the event but the effect turned out to be temporary as it was caused by bleeding into his interocular fluidin his later life stapp would become a major promoter of enhanced automotive safety he chaired the john p stapp foundation for automotive safety and later worked with the national highway traffic safety administration on the development of improved crash test methodsin 1979 stapp was inducted into the international space hall of fame and in 1991 stapp was awarded the national medal of technologystapp died in 1999 at age 89despite this video coming from the history channel it is actually fairly accurate

a beautiful explosive science experiment andy takes to the prep room to make a whoosh rocket with a water bottle and some ethanolsubscribe for regular science videos: http:bitlyrisubscribeandy investigates how much thrust his water cooler rocket can generate he finds out how to make a rocket with ethanol propanol and methanol and a large water container but how powerful is the rocket can a bottle rocket propel a person or can it only make its own weight move andy experiments in the lecture theatrethe blue flame you see at first is a sign of complete combustion when abundant oxygen reacts with the fuel producing just the classic combustion products of carbon dioxide and water as the oxygen supply is consumed carbon particles start to be released which cause the yellow flame the pulses of flame that appear in the bottle towards the end of the reaction are probably created as fresh oxygen is drawn in from the top and mixes with the remaining fuel watch amazing slow motion footage of the explosionthis beautiful experiment is also a great example of a simple rocket a device for creating force by pushing the products of fuel combustion in one direction andy takes to the lecture theatre to investigate whether the force is enough to push him on a swing he tries to determine how much force is being generated and experiments with different fuels he experiments with ethanol methanol and propanol to find out how to make the best bottle rocketsubscribe for regular science videos: http:bitlyrisubscribewatch more science videos on the ri channel http:richannelorgthe ri is on twitter: http:twittercomri_scienceand facebook: http:wwwfacebookcomroyalinstitutionand tumblr: http:ri-sciencetumblrcomsubscribe for the latest science videos: http:richannelorgnewsletter
