The largest flower in the world, the rafflesia arnoldi, weighs 7 kg (15 pounds) and grows only on the Sumatra island of Indonesia. Its petals grow to ? metre (1,6 feet) long and 2,5 cm (1 inch) thick.
There are 16 species of rafflesia, found in Sumatra, Malaysia and Borneo. The species is named after the naturalist Sir Stamford Raffles, who founded the British colony of Singapore in 1819. Raffles discovered the parasitic plant with his friend Dr. Joseph Arnold during their travels in May 1818. The rafflesia arnoldi is named after the two.

Several species of Rafflesia grow in the jungles of Southeast Asia, all of them threatened or endangered. Rafflesia arnoldii is the largest; its blossom attains a diameter of nearly a meter and can weigh up to 11 kg. Not only is it the world’s largest flower, it is one of the most bizarre and improbable organisms on the planet.
It produces no leaves, stems or roots but lives as a parasite on the Tetrastigma vine, which grows only in primary (undisturbed) rainforest. Only the flower or bud can be seen; the rest of the plant exists only as filaments within its unfortunate host. The blossom is pollinated by flies attracted by its scent, which resembles that of carrion.
The Rafflesia is rare and fairly hard to locate. It is especially difficult to see in bloom; the buds take many months to develop and the blossom lasts for just a few days. How many of these strange plants still survive is unknown, but the last of them can be expected to vanish as the remaining primary forests of Borneo and Sumatra are burned.

Glass Bridge will be suspended 4,000 feet above the Colorado River on the very edge of the Grand Canyon. On May 2005, the final test was conducted and the stucture passed engineering requirements by 400 percent, enabling it to withstand the weight of 71 fully loaded Boeing 747 airplanes (more that 71 million pounds).

The bridge will be able to sustain winds in excess of 100 miles per hour from 8 different directions, as well as an 8.0 magnitude earthquake within 50 miles. More than one million pounds of steel will go into the construction of the Grand Canyon sky walk………………

The first blonde answers, “That’s easy, we’ll catch him fast because he only has one eye!”

The policeman says, “Well…uh…that’s because the picture shows his profile.”

Slightly flustered by this ridiculous response, he flashes the picture for 5 seconds at the second blonde and asks her, “This is your suspect, how would you recognize him?”

The second blonde giggles, flips her hair and says, “Ha! He’d be too easy to catch because he only has one ear!”

The policeman angrily responds, “What’s the matter with you two?! Of course only one eye and one ear are SHOWING because it’s a picture of his profile!! Is that the best answer you can come up with?

Extremely frustrated at this point, he shows the picture to the third blonde and in a very testy voice asks, “This is your suspect, how would you recognize him?” He quickly adds” . . . think hard before giving me a stupid answer.”

The blonde looks at the picture intently for a moment and says, “Hmmmm . . . the suspect wears contact lenses.”

The policeman is surprised and speechless because he really doesn’t know himself if the suspect wears contacts or not. “Well, that’s an interesting answer . . . wait here for a few minutes while I check his file and I’ll get back to you on that.”

He leaves the room and goes to his office, checks the suspect’s file in his computer, and comes back with a beaming smile on his face. “Wow! I can’t believe it…it’s TRUE! The suspect does in fact wear contact lenses. Good work! How were you able to make such an astute observation?”

“That’s easy,” the blonde replied. “He can’t wear regular glasses because he only has one eye and one ear.
