Top 10 Tiny Animals With Enough Poison To Absolutely Destroy You
Most people would steer clear of any snakes or over-sized spiders that crossed our paths. We have a sort of logic when it comes to animals that tells us “Bigger = Deadlier.” And in the case, say, a King Cobraversus a garden snake, that argument checks out.
But more often, you will often find that the opposite is true. Many animals make up for their small size with deadly venom, and so what may look like a regular snail could actually be your final downfall. Below are ten tiny, but incredibly deadly, animals.
10. Sonoran Coralsnake
These snakes, related to cobras, are found in the deserts of Mexico and the Southern US. While they can grow to about two feet, they usually don’t, and are much smaller and skinnier than most other snakes. As if they’re not hard enough to see, due to their size, they tend to be nocturnal.
Lucky for us, they prefer to indulge in cannibalism, snacking almost exclusively on other snakes. But if you do decide to pick one up and play with it, beware: their venom is a powerful neurotoxin that can paralyze your central nervous system.
9. Blue Ringed Octopus
Try to forget about starting another grammar war over whether it’s “octopuses” or “octopi,” and try to focus on how this thing will straight-up kill you. The Blue Ringed Octopus can be found in the waters aroundAustralia, and measure up to a whopping 4 inches in size. Usually it is a brown or yellow color but, when frightened, its blue rings will light up all over its body.
However, as pretty as it is, do not touch! The tiny critter has an incurable venom toxic enough to kill 26 adults humans in a matter of minutes.
8. Brazilian Wandering Spider
So called because they hunt prey, as opposed to spinning webs, the Brazilian Wandering Spider has been recognized since 2007 as the spider with the most powerful venom in the world, and the one responsible for the most human deaths. Most victims will die within an hour of being bitten.
The spider, which can grow to have a leg span of 4 inches, is also known as the banana spider, as it tends to hide inside between bunches of bananas and then jump out at their prey. In 2008, one was found in a crate of bananas in Britain. It was caught with a pencil, since that’s logically the best tool to approach the most dangerous spider alive with, before humanely putting them. By that, we naturally mean “blow them up as violently as possible.”
7. Deathstalker Scorpion
Deathstalker scorpions are mainly found throughout Africa and Asia in mainly dry, desert habitats, measuring up to 4 inches, but usually around 2. They are considered to contain among the most powerful and painful scorpion venom in the world, which can cause fever, convulsions, paralysis and death.
When it comes to scorpions in general, the smaller the pincer, the more powerful the venom. While many people would probably assume the opposite, this is because those with large pincers can rely on the force of their bite to get their message across, while those with small ones need toxins to defend themselves.
6. Tarantula Hawk
Actually a type of wasp, there are 15 species of tarantula hawks in North America, and they can grow to be about 2 inches long. They are so called because they hunt tarantulas, stinging and paralyzing them. The Tarantula hawk will then lay eggs in the spider, and bury it alive. When the eggs hatch, they will eat the spider alive for 35 days.
So unless you’re a tarantula, that’s not something you need to worry about. But that doesn’t mean you have nothing to worry about, since its venomous sting is meant to be the second-most painful sting in the animal kingdom.
Interesting Geography Facts
Alaska
More than half of the coastline of the entire United States is in Alaska.
Amazon
The Amazon rain-forest produces more than 20% of the world's oxygen supply.
The Amazon River pushes so much water into the Atlantic Ocean that, more than one hundred miles at sea off the mouth of the river, one can dip fresh water out of the ocean.
The volume of water in the Amazon river is greater than the next eight largest rivers in the world combined and three times the flow of all rivers in the United States.
Antarctica
Antarctica is the only land on our planet that is not owned by any country. Ninety percent of the world's ice covers Antarctica. This ice also represents seventy percent of all the fresh water in the world. As strange as it sounds, however, Antarctica is essentially a desert.
The average y early total precipitation is about two inches. Although covered with ice (all but 0.4% of it), Antarctica is the driest place on the planet, with an absolute humidity lower than the Gobi desert.
Brazil
Brazil got its name from the nut, not the other way around.
The Future of Education

Google, Cyborgs, and the Future of Education
By: Joe Federer, TeachHUB.com
Beyond the information revolution: How will technology change the classroom?
It’s been an interesting week in science and technology – from the mind-controlled bionic hand that can sense what it’s holding to the human ear created using a 3D printer and live cells to the announcement that Google Glass, Google’s augmented reality glasses, will hit shelves sometime in 2013.
At first glance at a product like Google Glass, many teachers may ask themselves - Well how do we keep kids from cheating if all of the information in the world is available in the periphery of their glasses? But that question has built into it an assumption about education which may not be true for long.

Largest Gun Ever "Gustav Gun"
 |
| Hitler looking at the Gustav Railway gun. |
Two types of projectiles were fired using a 3000lb. charge of smokeless powder: a 10,584 lb. high explosive (HE) shell and a 16,540 lb. concrete-piercing projectile. Craters from the HE shells measured 30-ft. wide and 30-ft. deep while the concrete piercing projectile proved capable of penetrating 264-ft. of reinforced concrete before exploding! Maximum range was 23 miles with HE shells and 29 miles with concrete piercing projectiles. Muzzle velocity was approximately 2700 f.p.s.
Three guns were ordered in 1939. Alfried Krupp personally hosted Hitler and Albert Speer (Minister of Armaments) at the Hugenwald Proving Ground during formal acceptance trials of the Gustav Gun in the spring of 1941. In keeping with company tradition, Krupp refrained from charging for the first gun - 7 million Deutsch Marks were charged for the second (named Dora after the chief engineer's wife).
Thousand Year Old World’s Largest Cashew Tree- Maior Cajueiro do Mundo.
In 1994, the Guinness Book of Records set aside a separate column for the world’s largest cashew tree called Maior Cajueiro do Mondo located in Natal, Brazil. The gigantic tree has grown from an amalgamation of two genetic tissues. Such tissues allow the branches of the tree to grow outwards rather than upwards. Gradually, hence, the branches tend to stoop towards the ground and eventually make for a root. This new root further grows into a new tree.
The massive tree occupies 80,000 square feet of land or roughly five acres. It is guessed to be around thousand years old. One can easily climb a tower to view this tree from a vantage point or for that matter, even climb up through the roots.
You can heartily go and pay a visit to this enormous work of nature. However, beware of the orange caterpillars. These gorgeous looking insects are poisonous. They swamp over the tree seasonally and are a size of a finger.
The beauty of this tree is that it produces 60,000 pieces of cashew fruit each year. As for some people it may come as a surprise that a cashew nut is not the fruit but a single nut is attached only to the bottom of the fruit!

Amazing Peacock Spiders
In Australia there are many species of Spider,
but one very small variety, found so far only in Queensland and New South
Wales, is ‘Maratus Volans’. Also known as the Jumping Peacock Spider, the
miniature males have truly amazing colours of iridescent red, green and blue,
among others. The head and breast parts of this spectacular beast are usually
very dark with red stripes, while the upper abdomen area is green, blue and
red. That is not the end of the story, however, because, like peacocks, male
spiders also possess a sort of cape or flap around their abdomen which they can
raise for display whilst courting.
These
dramatic-looking spiders may seem like they're getting ready to attack, but
this colorful display from male peacock spiders is in fact a mating ritual.
Similar to
peacock birds, where this spider gets its nickname from, the male flashes it’s
brightly colored, iridescent stomach flaps in a bid to attract females. And even if these arachnids did attack, they
wouldn't get far because the adults only grow to about 5mm long.
Male peacock
spiders extend their legs and flash their colorful, iridescent abdominal flaps
to attract a mate.
Peacock
spiders are members of the jumping spider’s family, renowned for being tiny.
Adults only grow up to around 5mm in length.
While the
male peacock spiders carry out their mating ritual, the females carefully study
the coloring, vibrations and movements to make sure the potential suitor is
healthy and the correct species to mate with.
This is the
Maratus harrisi species of peacock spider that is traditionally found in the
Namadgi National Park in New South Wales. The ruler is shown for scale.
When a male
peacock spider senses a female it will begin the mating ritual by lifting its
legs and flashing its stomach in a sequence that looks like a dance routine.
The females
carefully study the coloring, vibrations and movements of the male to make sure
the potential suitor is healthy and the correct species to mate with.
Once he has
mated, he will repeat this dance with as many females as he can find and
Maratus spiders can have multiple partners at one time.
There are 20
known species of peacock spiders living in Australia, yet they're so hard to
come by only eight have been formally identified.

DNA Basics !
What is DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
All you need to know about "The 5-second rule"
Almost everyone has dropped some food on the floor and still wanted to eat it. If someone saw you drop it, he or she might have yelled, "5-second rule!" This so-called rule says food is OK to eat if you pick it up in 5 seconds or less.
Believe it or not, scientists have tested the rule. We're sorry to report it's not necessarily true. Bacteria can attach itself to your food even if you pick it up super-fast. But will your dropped food contain enough bacteria to make you sick? It's possible — and that's why you shouldn't eat food that has hit the floor.
Here's what you need to know about the 5-second rule:
A clean-looking floor isn't necessarily clean.
A floor that looks dirty is usually worse, but even dry floors that look clean can contain bacteria. Why? Some germs can survive on the floor for a long time. And unless you have a powerful microscope, you can't check to see how many germs are there. So chances are, some bacteria are probably living on your kitchen floor and the cafeteria floor at school.
