Son doong cave is a cave in Phong Nha-Kẻ Bàng National Park, Bố Trạch district, Quảng Bình Province, Vietnam. Currently the biggest known cave in the world, the cave is located near the Laos-Vietnam border. Inside is a large, fast-flowing underground river.
In early August 2013, the first tourist group explored the cave on a guided tour at a cost of US$3,000 each. The group had six members from Australia, Norway, Russia and USA and spent 7 days and 6 nights for the tour. Next exploration trips will be arranged.

Split Apple Rock is a geological rock formation in The Tasman Bay off the northern coast of the South Island of New Zealand. Made of granite, it is in the shape of an apple which has been cut in half. It is a popular tourist attraction in the waters of the Tasman Sea approximately 50 metres off the coast between Kaiteriteri and Marahau. The rock sits in shallow water at low tide and is accessible by wading. It is also a point of interest for the many tourist boats and pleasure craft which operate along the shores of the Abel Tasman National Park. The cleft to produce two sides of the 'apple' was a natural occurrence. It is unknown when this happened and therefore the cleaving of the rock has attracted mythological explanations.

Ever wonder what a human head would look like if he or she was turned into a pastry? Well now you can, thanks to the works created by the photographer Brandon Voges. Some of the pictures are light and funny, while others are pretty gruesome and outright disgusting. For example, the comparison of an old lady with some chunky, orange-colored pastry coated with what looks like syrup, really makes you lose your appetite. It is a wonder how they decided to use such an unappealing picture to promote an annual food show of the National Restaurant Association. (Photo by Brandon Voges)

A woman is cooled down with a watering can as she sunbathes using insulating tape, at a beauty center in Belo Horizonte, Brazil, on December 21, 2017. Brazilian women take advantage of the beginning of the summer to sunbathe using the new national trend: natural tanning with insulating tape. Instead of using tiny bikinis on the beach, women avoid being bothered or stalked by getting taped in the shape of them, and lay in the sun over rooftops to enjoy the morning sun and get the perfect “marquinha” tan lines.
