Science is one of those things that can either become really boring or something that can be perceived as magic. It is all in how you look at it and if you want to give your kids a better outlook on science or if you want to encourage their budding interest in the subject, why not try out some experiments at home? Watching science in action is not only education for the kids but it is also highly entertaining and gives them something better to do than watching TV. Science experiments need not be overly complicated and below are some examples of amazing science experiments you can do at home.
This experiment is a lesson in reaction and the resulting foam is safe to touch. To get started, grab a soda pop bottle and set it in a tray to avoid making a mess. In a separate bowl, mix a tablespoon of yeast and two tablespoons of warm water. This mixture will help speed up the reaction.
In your soda pop bottle, pour in half a cup of hydrogen peroxide (6%). Choosing 8% will work too but if you get the 3%, it may not work as well. A few squirts of dish soap and some food coloring in the bottle and you are done. Pour in your yeast mixture in the bottle and watch magic happen! If you are performing this with older kids, they might have questions and it can be summed up in this formula that you can ask them to research: 2 H2O2 –> 2 H2O + 02.
Lava lamps are groovy and if you have ever seen one in the stores and balked at the price, you can easily make one on your own and you can ask your kids to make it with you. It is a fun experiment that teaches them how oil and water do not mix. The result is just as groovy as a lava lamp you see in stores but so much cheaper. For this recipe, you need a clear and clean bottle, vegetable oil, water, food coloring, and effervescent tablets like Alka Seltzer. Fill your bottle with oil halfway and then add water. Make sure you have an inch of space left on top and add 10 drops of food coloring. Break your antacid tablets in quarters and drop them in one at a time. Make sure all the bubbles are gone before capping the bottle. The bubbles will move the globules of oil around and this will give off that lava lamp effect. This will teach your kids how oil and water do not mix and it makes for a nice room accessory.
These experiments are so much fun and very easy to do. Chances are, you already have the materials that you need and even if you do not have them, you can easily find them in your local stores. They are also safe to perform and you can manage the experiment with kids of all ages and never have to worry.

The world as we know it today is convenient and fun to be in because of certain inventions which have made all the difference from being medieval to being modern man. Here are the 5 most important inventions of all time which have truly made their own marks in history.
The name of the inventor should surely ring a bell. Alexander Graham Bell thought of how to communicate even from afar by converting the human voice into electric signals. He was the proponent of long-distance communication, and his development of the telephone had been the forerunner of the communication convenience we all experience today.
There is no single man who can be truly credited for the discovery of electricity, but some of the names which would pop up in the list include Benjamin Franklin and his kite experiment, and Nikola Tesla who is often dubbed as the father of electricity because of his understandings of this force behind most of the everyday items which we use today. From home entertainment to the lights outside the road, electricity is behind it.
Traveling by ship was okay. But traveling by air has proved to be much better. To get to other foreign destinations faster, the best way today is by plane and we owe it to the Wright brothers who had invented it back in 1903 when they had successfully made the first sustained flight. Abbas Ibn Firnas back in the 9th century had made his own attempts but they weren’t able to last. Only the Wright brothers were able to give way to the birth of the modern winged aircrafts.
• Light bulb
Imagine being in a room. A dark room. Candles can give you light but that light just isn’t enough in the dead of night. Thankfully, Thomas Edison did not give up even if it had taken him almost a hundred tries before he had perfected his invention of the light bulb back in 1978. Joseph Swan made a light bulb in 1860 but since it glowed only for just a few hours, Thomas Edison is the one credited for the invention of the light bulb as we know it.
• The Worldwide Web
You wouldn’t be reading any of this if not for the invention of Sir Tim Berners-Lee’s invention – the worldwide web. Accessing the websites you know today traces its origins back to the English engineer’s invention!

People born with dwarfism may not have it as bad today as they did several decades back. After all, with society being more open to accepting them, they are able to function just like people born without dwarfism. They can go to school to get an education, they can hold down jobs, and they can even start families. Some of them even star in movies and nab prime, juicy roles. Indeed, life is good for people with dwarfism though some limitations are enforced on them due to the fact they their condition hinders them from doing everyday tasks like normal people.
Abnormally short limbs and arms, extremely bow legs, and similar defects can make it hard for people with dwarfism to accomplish day to day tasks but a radical technique may just be the answer to their problems. This radical technique is actually a limb-lengthening procedure of which there are different types and they all go by different names. They are all accomplished in varying ways but one thing they all share in common is they involve serious pain and serious commitment from the patients and their families. After all, if bones are to be broken on a regular basis and adjusters need to be looked after every day, it is easy to see why this procedure is no small feat.
Limb lengthening procedures (Vilarrubias technique or Lizarov technique) involves people with dwarfism to go to doctors who then break the bones in their thighs or in the thighs, shins, and arms so new bones can grow and thus give the individual an extra 6-inches or 12-inches of height. Some patients with achondroplasia who have normal sized torsos but really short arms and legs even have their arms broken wherein they gain an average of 4 inches. According to experts, undergoing this procedure gives them the chance to lead more normal lives and have healthier interactions with people; it also helps their self-esteem.
However, not every person born with dwarfism is necessarily down with this technique because not only is it excruciatingly painful but it also has some very serious side effects and risks. Patients who undergo limb-lengthening procedures undergo the risk of nerve damage, infection, increased contractures in the hip, knee and ankles, and late onset osteoarthritis.
However, some people with dwarfism feel this is the only way they can lead full lives free from the limitations their condition has set upon them. The dwarf community may be divided but there is no denying that these procedures have some remarkable results.

A lot of people often think of hypnosis as nothing more than a magician’s trick or a sideshow act at a carnival. And who can blame them? Because after all, these are the two places where they hear about it and see it being done. However, what they do not know is that hypnosis — or hypnotherapy as it is also called — has some very real health benefits. It can help people accomplish simple tasks such as remembering names and it can also change their lives completely. To know more about the benefits associated with hypnotherapy, read below.
Hypnotherapy can treat addictions — Addictions are really quite hard to quit but introducing hypnotherapy can make quitting easier. It doesn’t matter if you are hooked on smoking, drugs, or food because by undergoing hypnosis, your body gets the help it needs to get rid of physical addictions. And what is nice about hypnotherapy is that there is solid proof that it can permanently get rid of addictions and lessen the chance of a relapse.
Hypnotherapy for weight loss — When you want to lose weight and all the diets and exercise in the world just don’t bring you the results you want, it may be a good idea to add hypnotherapy to the mix. Research has shown that it is about 30% more effective in promoting weight loss as compared to diets. Medical experts believe it is because hypnosis or hypnotherapy helps people who have a tendency to overeat to prevent doing so. This is what helps them lose excess weight.
Hypnotherapy for chronic pain— Chronic pains can be quite troublesome and though they can be managed with medication and therapy, adding hypnotherapy to the whole treatment may just bring about the very best results. In fact, when all the drugs and therapy in the world just aren’t doing anything to eliminate your pain, it may be time to turn to hypnotherapy since nearly all experts agree that it works when drugs fail.
In a nutshell
Those are just some of the many benefits hypnotherapy can bring to you so try it out sometime. However, you need to keep in mind that there are occasions when it might not work since for hypnotherapy to work, the person undergoing it has to crave real change and want real results. And furthermore, you have to remember that several sessions are needed before any significant results can be seen, because contrary to popular belief, hypnosis is not magic and will not perform miracles overnight.

Think of what you know about outer space— stars, planets, asteroids, black holes, and space junk. Those pretty much sum up what the average person knows about what is floating out and about in outer space. But take note, the universe is a vast and immense space, making it possible for it to harbor strange things that you wouldn’t believe exist. To get to know some of these bizarre things, read on.
Quasars. Quasars are beacons of light that shine on our planet and are believed to be located right at the very edge of the universe. Most scientists believe they are massive black holes found in the hearts of very distant galaxies. . What is so fascinating about them is that they tell scientists exactly how the universe came to be. Another amazing thing about quasars is that the amount of energy they release equals to more than the energy released by a hundred galaxies put together. The picture of the quasar provided above is that of 3C 273 and was taken way back in 1979.
Cannibalism. Just like some plants, animals, and people on earth who eat their own kind, galaxies can “eat” one another as well and thus evolve over time. One example is Andromeda, a galaxy near the Milky Way Galaxy that is currently making a meal out of one of its satellites. This galaxy is not a very neat eater, though, because all around it are dozens of star clusters that are remnants of her past meals.
Exoplanets. There was a time when the only planets everyone knew about were the ones found in our solar system. However since then, more and more planets have been found by astronomers, and to date, they have found more than 500 exoplanets scattered all over the outer space. What makes these extra-solar planets interesting is that they range from being gas giants that are bigger than Jupiter to being tiny rocky planets that orbit around red dwarfs.
The outer space is literally infinite. However, with the leaps and bounds made in technology, who knows what scientists may discover in the next several years? But without question, they are bound to be exciting! And whatever they will be, we can be sure the people of planet Earth are in for great discoveries.
