Why not create a trash bin which will consist of several disposable and recycled paper containers nested inside one another? This will eliminate the need for plastic can liners. Such a bin would be the ideal choice for disposing of paper products, since the contents and bag could all be recycled together. It would also be suitable for dry biodegradable materials, and could be used in compost bins.

The idea is to create vibrating belts which will make it possible for soldiers to follow directions and find their way through the darkness. The belt will contain eight mini actuators that will represent the eight cardinal directions. A GPS system, compass, and accelerometer will be able to track the direction a soldier moves, and provide a gentle, vibratory nudge to help keep him on the correct path.

The idea is to create a palm sized hearing device that will include an array of noise management systems but will look like a common mp3 player. The device will be easy to use, featuring an LCD screen and headphones with integrated microphones. It will include noise reduction and will be able to control feedback and wind noise. The device will also include a special function that will adjust to the changing environments of standard, music, indoors, and party.

The vibrating suit will provide haptic feedback to help athletes develop muscle memory. The suit will use an array of vibrating motors to send feedback to the user as to their body's position in space. The motors will signal in real time when the athlete is outside the desired range, and the data will be also recorded for later study.

The idea is to create a device which will be useful for people with visual disabilities. This device will be capable to scan ordinary text and convert it into Braille on the surface of this mouse-like device. If the idea realized it would be much easier for people with visual disabilities to read most of what sighted people can.

So, this is for all the modern, edgy, punk youth out there. Or possibly weird, zany, old people. Basically, it's just coloring highlighter on your eyelids as eyeshadow. It's very cool. It brings out the color of your eye with he contrast. I tried it on my friend, and the only advise I can give you, if you try it, is to avoid rubbing it in your eyes! If I were to ever make this idea into something, I would start by calling it EyeLighter. Get it, the play on words... Anyway, then of...

Why not develop a personalized onboard system to monitor chronic disease and personal wellness? The new system will be designed to react to simple voice commands, and will be able to deliver information on environmental aspects affecting allergies or monitor the blood sugar of diabetics through wireless glucose monitors. The system will also recommend alternative routes, suggest a snack, or roll up the windows in case of smog.

To have a pleasant odor in a room, you need to drip a couple of perfume drops on an unlit light bulb. If there is a musty smell in your fridge, you have to put black bread slices on the shelves and hold them in a closed refrigerator for several hours. To get rid of a specific smell in the place where the bread is kept, you need to wipe this place with a cloth dampened with vinegar from time to time and air it regularly. Unpleasant odors in a cupboard can be removed...

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.

The stains of organic origin are removed with stain removers, which include reducing agents (sodium hydrosulfite or its derivatives), oxidants (hydrogen peroxide), as well as various solvents and other substances. Their action is based on the fact that they convert coloring matter to the colorless one which is easily washed out. To remove stains from juice, berries, fruit, ink, wine from any fabric use powdered cleaners and pastes, indicating that the stain remover is used for...
