This light is bent and reflected, like a reflection in a mirror, and this causes all of the amazing colors that you see. Rainbows normally appear from the rain, but they can happen wherever light is being bent...

Mole Concept What is the Mole Concept? The mole concept is a convenient method of expressing the amount of a substance. Any measurement can be broken down into two parts – the numerical magnitude and the units that the magnitude is expressed in. For example, when the mass of a ball is measured to be 2 kilograms, the magnitude is ‘2’ and the unit is ‘kilogram’. When dealing with particles at an atomic (or molecular) level, even one gram of a pure element is known to contain a huge number of atoms. This is where the mole concept is widely used. It primarily focuses on the unit known as a ‘mole’, which is a count of a very large number of particles. What is a Mole? A mole is defined as the amount of a substance that contains exactly 6.02214076 * 10 23  ‘elementary entities’ of the given substance. The number 6.02214076*10 23  is popularly known as the Avogadro constant and is often denoted by the symbol ‘N A ’. The elementary entities that c...

History of Toy Balloon - Who Invented the Rubber Balloon? Toy balloon is a small balloon made of rubber or aluminized plastic and inflated with gas, usually air or helium. It is mostly used for child play, party decoration, and in advertising. Their sizes typically vary from 10 to 30 centimeters in diameter but can be made in any size or shape. Toy balloons can look like a relatively modern invention, but their variations existed for centuries. There are illustrations from the 14th century that depict balloons made from inflated pig bladder. Galileo also used an inflated pig's bladder in an experiment in which he tried to measure the weight of air. Michael Faraday invented the first rubber balloon in 1824. He used them in experiments with hydrogen at the Royal Institution in London. He made a rubber balloon out of two sheets of rubber which he covered with flour on the inside so they would not stick to each other but leave edges uncovered and pressing them together. Rubber...

Kitten Care: Must-Know Tips for Raising Kittens When it comes to raising kittens, the philosophy is pretty similar to that of bringing up children. If you provide proper care and training when they’re young, it increases the odds they’ll grow up to be healthy, well-adjusted adults. So if you recently adopted a kitten, start incorporating this advice as soon as possible. MJ the kitten. 1) Don’t Treat Your Kitten Like an Adult Cat Just as a human infant has vastly different needs than a teenager, a kitten will have care requirements distinct from those of a fully matured cat. In addition, you should consider a kitten’s various stages of development when caring for her: Under eight weeks of age.  At this early age, a kitten should still be with her mother and litter mates. Because kittens this young are unable to regulate their own temperatures, they rely on one-another’s body heat to survive. In addition, they are still developing vision and leg coordination. If you...

Raising a Puppy: Things to Consider Puppies are little bundles of energy who are often intensely curious about their surroundings. Life with a puppy is not that different from life with a human toddler—you'll need a lot of patience as you watch over your pup to keep him out of trouble, instruct him in appropriate behavior and safely teach him about the world. The good news is that puppies sleep a lot, although they don't always sleep through the night, and your pup may wake the household whining and barking to express his displeasure at being left alone. Puppies are also driven to chew a lot as their adult teeth come in, and may see the doggie version of a teething ring in the living room rug, the couch, your favorite pair of shoes and even your hand. If you become frustrated with your new pet, it's important to remember that the task of raising a puppy is temporary. He'll be all grown up by his first birthday, and he'll leave most of his puppy tendencies behi...
