1) Did you know that this colourful little chap is the Costa Rican Variable Harlequin toad aka the Clown frog. 2) Did you know that the Karni Mata Hindu Temple in Rajasthan, India, is also known as the Temple of Rats. The temple is famous for the approximately 25,000 revered black rats that live there. Visitors play with and feed the rats and even sometimes drink from the same milk and eat the same food. 3) Did you know that vanilla flavoring is sometimes made with the urine of beavers. 4) Did you know that Botox is made from botulinium toxin which is considered the most deadly substance in the World as half a pound would be enough to wipe out the entire World population. Almost all the Botox in use throughout the World is made in one single factory in Ireland. 5) Did you know that tuna swim at a continuous steady rate of about 14km per hour for their whole life until they die. Whilst alive they never stop moving as if they stop they are unab...

Pimples are one problem, which is up on several women's list of skin concerns. The problem isn't restricted to women,  Men and some teenagers are equal sufferers.  Here are 5 natural ways with which, one may keep pimples at bay.  1.FOOD TO AVOID •Avoid red meats and if you can't avoid non-veg food. Along with this, it's important to avoid certain foods.  •Say a firm no to sweets, fried foods, heavy oily and gravy dishes, chocolates, ice-creams and aerated drinks at all cost.  •Youngsters quench their thirst with colas, instead of water and their parents not saying anything at all. Never do this and if you are a parent, never allow this to happen.  •Teach your youngsters from an early age to eat green vegetables, fruits and drink plenty of water, it may be difficult at times, but believe me , they will thank you in the long run.   2.KEEP YOUR STOMACH CLEAN • Let's talk about the internal care. If you have been suffering from...

Any bowling alley works through a combination of a wooden or synthetic lane fl anked by semicylindrical gutter channels, an automated pinsetter machine and ball sorter, and a return ball gully and stacker. The glossy, 60-f00t lane is normally constructed out of 39 strips of sugar maple wood, which itself is coated with varying layers of oil down its length. This coating is often heavy towards the bowler end, before dissipating down the alley. This allows a spinning ball more purchase in the fi nal quarter of its journey, enabling pro-bowlers to hit the pins at varying angles. At the pin end of the alley, starting at the termination of the lane, lays the pin-deck. This deck is where the pins are set up and knocked down, and thanks to this constant activity, it is coated with a durable impact-resistant material. Behind the deck lies the fi rst part of the mechanical pinsetter machine. The pit and shaker collects both the fallen ball and pins before shuffl ing them to its rear and into m...

How does a large glass cylinder become a tiny thread of fl exible glass? The tiny filament of glass at the core of a length of optical fiber starts out as two tubes. These tubes are made from fused quartz glass, which is mainly silica to give it flexible properties. First the glass tubes are dipped in corrosive hydrofluoric acid to remove any oily residues, they are then placed in a pair of lathes that spin and heat both tubes with a hydrogen and oxygen flame. When the tubes turn white they are nearing peak temperature and at 2,000°C the tubes melt together to form one longer tube.  This longer tube is placed in another lathe where it is turned and heated by a burner before being injected with chemical gases containing liquid forms of silicon and germanium. The heat and gases cause a chemical reaction that leaves a fine white soot inside the tube. As the burner travels up and down the length of the tube the soot fuses to create a solid glass core. The outer glass tube will for...

Water has been used to power man-made mechanisms for hundreds of years, mostly in food production in the form of a mill wheel to grind corn. However, using the kinetic energy of water probably became a reality earlier than you thought. In 1878, inventor Lord Armstrong lit his home in Northumberland using only the power of a nearby waterfall. It’s not until the latter half of the 20th Century that we began to take advantage of the massive potential of hydroelectric power. Intriguingly, both the dirty and environmentally unfriendly coal power plants and clean, green hydro-power use almost identical technology to generate power. Central to a coal-fi red plant is a turbine: coal is burned to produce heat energy, which is used to boil water into steam, which then drives a turbine. Hydroelectric power removes the coal and steam elements and instead, fl owing water turns the blades of each turbine.  By damming a river next to a drop in elevation and releasing a co...

Discover how to get milk from a cow The milk is extracted using a vacuum applied to the cow’s teats. Milk stored in the udder is drawn into a system of pipes leading to a receiver tank where the milk is collected before being passed to the cooling tank. A ‘cluster’ of four teat cups – each consisting of a stainless steel shell, a fl exible rubber lining and a short pulse pipe – are attached to the teats. Between the outer shell and lining is a pulsation chamber that collapses with the addition of air from a pulsator. When the chamber is devoid of air (milk phase) a vacuum is created, which gently draws milk from the teat. When the chamber is fi lled with air (rest phase) the lining of the teat cup collapses and massages the teat. Continued repetition of these phases not only aids milk production by mimicking the action of a suckling calf, it also promotes blood circulation. To help the milk fl ow away through the pipeline, once out of the cow the milk is mixed with air added by...

Shattering the science behind what makes the breakable unbreakable Bullet-resistant glass works by absorbing a bullet’s kinetic (movement) energy and dissipating it across a larger area. Multiple layers of toughened glass are reinforced with alternated layers of polycarbonate – a tough but fl exible transparent plastic which retains the see-through properties of glass. As a bullet strikes the fi rst glass layer, the polycarbonate layer behind it forces the glass to shatter internally rather than outwards.  This process absorbs some of the bullet’s kinetic energy. The high velocity impact also fl attens the bullet’s head. Imagine trying to pierce through a sheet of cotton with the top end of a pencil. It would be very diffi cult compared to using the sharp pointed end. The same principle applies here. The fl at-headed bullet struggles to penetrate the layer of polycarbonate. As the bullet travels through each layer of glass and polycarbonate, the process is repeated until it no l...
