It would be awesome to have a foldable badminton racket. Folding may impact the strength of the racket but this seems to be resolved by the racket design.

How about a lotion that blocks cold temperatures from hitting our skin? You rub on the lotion and it keeps you warm :). The lotion will be of great help for people living in very cold climates. One could take it while hiking in the mountains or swimming in cold water without a wet suit. It can be also useful in emergency situations like when the power goes out in the winter and you cannot heat your house.

Inspired by the life vests used on airplanes, I suggest creating the world's first inflatable wetsuit. The wetsuit will inflate when the wearer pulls a cord that will cause a CO2 cartridge to inflate an air bladder located on the back of the suit.

The privacy pop is a tent for a bed, providing a measure of privacy in shared sleeping quarters. The tent is easy to set up, and includes large entry openings on either side as well as window-like openings on both ends. It fits on standard and XL twin beds and is large enough for a full size adult to sit up inside, yet can also zip down to fit in a handy carrying case.

I want to have an umbrella that changes its color once the rain starts falling on it. The umbrella will start out in black and white but each rain drop will change its color. When the rain stops and the umbrella dries the colorful design will slowly fade back to the primary color. I suppose some dyes which work if water is applied should be used for such an umbrella creation.

The idea is to create a unique snowboard by cutting the board in half, allowing each foot to have independent control and opening the door to an array of new tricks. The boards will be made of traditional snowboard materials, and will be used with current snowboard bindings. Such a snowboard will allow the user to have the fun of a snowboard and the mobility of skis, without locked feet and bulky poles.

The new case for iPhones will let you keep your phone protected even while taking a call. The case will be equipped with a window and a proprietary touch-sensitive strip that will allow you to see who is calling and then take the call without ever opening the case's front cover. The flip-style case will be made of polycarbonate plastic and 'leatherette,' and will retain the phone's slim design.

The idea is to combine fishing pole and walking stick to make it a bit easier to access remote fishing spots. The device will feature an aluminum shaft that will store the fishing rod segments and serve as the hiking pole, with the handle for the fishing pole also functioning as the handle for the walking stick. The segments will be held in place by flick locks, and the device will be available in both fly rod and spinning rod varieties.

By combining three different base materials, the new 3D printer will be able to produce objects with a variety of colors and material characteristics. The printer will use three colors--cyan, magneta and yellow--that will be combined with other polymers to create objects that will feature combinations of soft, rigid or transparent qualities. The triple-jet technology will allow for hundreds of different color and material combinations (up to 45 different colors in one object),...

The new MP3 player will feature an all-in-one streamlined design, allowing more freedom of movement during water-based workouts and activities. The waterproof digital music device will be designed with the player housed within the earbuds, which will be held in place by a tension band around the back of the head. Volume and song playback will be accessed by the controls on the bottom of the earpieces, and the long-life battery time of 8 hours combined with the 4GB of music storage...
