Mystery Behind Japan’s Underwater Crop Circles Solved

Using underwater cameras the team discovered the artist is a small puffer fish only a few inches in length that swims tirelessly through the day and night to create these vast organic sculptures using the gesture of a single fin. Through careful observation the team found the circles serve a variety of crucial ecological functions, the most important of which is to attract mates. Apparently the female fish are attracted to the hills and valleys within the sand and traverse them carefully to discover the male fish where the pair eventually lay eggs at the circle’s center, the grooves later acting as a natural buffer to ocean currents that protect the delicate offspring. Scientists also learned that the more ridges contained within the sculpture resulted in a much greater likelihood of the fish pairing.

The Most Confusing Traffic Junction

The Magic Roundabout in Swindon, England, constructed in 1972, is the most brilliant and at the same time, the most confusing roundabout ever built. The roundabout consists of five mini-roundabouts arranged in a circle!

All they did was combine two roundabouts in one – the first roundabout sends traffic rotating clockwise and the second roundabout, which revolves inside the first, sends traffic anti-clockwise. Vehicles can enter or exit the inner roundabout using any of the five mini roundabouts placed at appropriate positions. The Magic Roundabout is so efficient that the average Swindonian can find his or her passage through one of the town’s busiest junctions with ease even at peak times. Forty years on, the Magic Roundabout still works, despite ever-increasing volumes of traffic.

1500 year old Hanging Temple

The Hanging Temple is built into a cliff (75 m or 246 ft above the ground) in Shanxi province, China.  The structure is kept in place with oak crossbeams fitted into holes chiseled into the cliffs. The main supportive structure was hidden inside the bedrock.  The temple was build to avoid flood, and use the mountain as protection from rain, snow and sunshine.
