Extreme tourism is at the height of its popularity today. This popularity is easy to be explained as extreme form of entertainment is the opportunity to experience the "thrill" that is missed in everyday life... this is emotions boom, risk and awareness of one's greatness and weakness. Extreme tourism is for the strong and courageous, for those who love risk and danger, who is not afraid to test his endurance. A new extreme attraction has been opened in the Australian city of...

I suppose that microscopic worms could do a better job of detecting explosives than X-ray machines, metal detectors or bomb sniffing dogs. The tiny nematodes, known as Caenorhabditis elegans, have little scent organs on the sides of their mouths. Why not extract the receptors from the amphids and incorporate them into a device (so called bomb sniffing machine).

If your dog or cat has fleas, get fresh pine shavings and let your pet sleep for several days at these shavings. Fleas cannot stand the strong resinous smell, so they run away quickly. There is another way to deal with fleas. Take tobacco (you can crumble cigarettes for this) and make tobacco decoction. Then give your pet a bath with this decoction. Of course, the animal won't like such a bath but after this procedure relief from fleas is guaranteed.

It is known that a basking shark feeds by swimming with its mouth open. The shape of the shark's body plays an important role in its efficiency as a feeder. A pressure differential is created as the shark swims, resulting in lower pressure along the shark's top and helping to draw water out of the shark's gills in a way that allows it to rely on the passive flow of water to feed. Why not design a turbine with the shark's design in mind? Water enters through the first turbine while...

It would be really cool to have a pet door that responded to a collar on your pet's neck only. If another cat or dog tried to get in, the door wouldn't budge. If your pet couldn't stay inside because of the heat or simply wanted to do its business in the yard, it would be easy to get out and return.

The idea is to develop a system that will allow pet owners a way to interact with their pets in real time by remotely controlling toys through the internet. The system will include a webcam, control box, and two devices that will be able to each move and swing a standard pet toy. Users will be able to log in and manipulate the toys from the on screen controls while watching their pet via the live webcam feed.

I am thinking of creating some fish saving device. It can be an aquarium which records the water temperature, ph level, oxygen level, amount of food eaten etc. and automatically fixes the problem by adding food and/or by adding oxygen or heating the water according to the settings defined.

Why not create a device that will combine a pet poop scoop with an incinerator, effectively turning pet waste into sterile ash in seconds? The device will consist of a retractable handle and an integrated decomposition chamber that will contain replaceable cartridges of as yet undisclosed chemicals. The pet waste will mix with the chemicals to become odorless, sterile ashes in under a minute.

It was proved that the bacteria in a sheep's stomach that enable it to digest cellulose can also help clean TNT contaminated soil. The TNT breaks down completely, leaving no trace in the animal's feces. Why not plant grasses in TNT contaminated soil and set the sheep free to graze and clear the land at the same time. According to my estimations, a flock of 20 sheep could completely clear an acre of TNT residue in less than three years.

I want an audio file on my phone which will frighten off mosquitos within a radius of 3.5 feet. A human won't hear anything but mosquitos will. The sound will be similar to the buzz of mosquito male which mosquito female try to stay away from.
