The changes in color on the main stalactite are actually optical illusions. The bit that looks darker is a slightly different color from the rest of the stalactite because it is wet however the submerged bit is exactly the same color as the rest, it is just all the underwater lights that make it look white. When the under water lights were turned off we could see it all looked the same. Also the water was surprisingly deep. It doesn't look it, but it is about 2m deep.

Cenotes Caves in Mexico

The Yucatan peninsula has virtually no surface streams due ot its limestone foundation -- a relic of its past life as coral reef on the bottom of the ocean. Ground water sinks through the porous limestone and travels to the sea in underground rivers and caves (formed from millennia of acidified water dissolving conduits in the limestone). To date, almost sixty cave systems with more than 300 miles of passageways have been discovered. These underwater streams can be accessed through Cenotes, sinkholes in the surface limestone. - SOURCE

Caves and Limestone Hills of Malaysia
Deer Cave, the world's largest passage, in Mulu National Park, Sarawak
David Bowden - 08 June 2006

Malaysia has some of the biggest and longest limestone caves in the world, some are archaeological sites, others are beautiful with stalagmites and stalactites, and maybe underground rivers. Some caves are home to a wide variety of cave fauna such as bats, swiftlets, snakes, and invertebrates.

Amongst the most famous caves in the world are the caves in Mulu National Park, Sarawak, which was inscribed as a World Heritage site in 2001. Some of the caves there are world record holders, such as Gua Nasib Bagus which houses the world's largest chamber - Sarawak Chamber. Clearwater Cave is the 10th longest in the world, at 110km. Deer Cave is one of the world's largest passages. The Niah Caves, also in Sarawak, is a famous archaeological site. A 40,000 year old human skull has been found there, and the rock paintings have been dated at 1200 years. Near Kuching the caves of Bau can be visited.

Japanese River  - Hole in the Water

October 10, 2007
Strange phenomenon seen in a lake in Eastern Japan...

Video: Hole in the Water

It is actually an art piece by Shiro Matsui:

It is the most fascinating of all the sculptures, IMHO. We stand there watching an empty space! From time to time the hole disappears briefly. The whole thing apparently weights 3 tons (presumably the underwater equipment, not the hole itself)

"With sculpture the original material evokes a sense of weight and gravity, which expresses a sense of reality. This characteristic is the unique power of sculpture. With painting two-dimensionality is a given, yet we are able to share the illusion of time and space. With my piece I am trying to merge these characteristics, by using real materials in the real world, yet having the power of illusion that painting holds."
