(The purple hue of the flame is presumably due to the heating of the potassium.). In the following demonstration, roughly equal amounts of solid potassium chlorate and sugar (in the form of finely powdered confectioner's sugar) are placed in a glass jar, and mixed vigorously.
Bluetooth is a technology that allows devices to communicate with each other without cables or wires. It is an electronics standard, which means that manufacturers that want to include this feature have to incorporate specific requirements into their electronic devices.These specifications ensure that the devices can recognize and interact with other devices that use the Bluetooth technology.hese devices include mobile phones, computers, and personal digital assistants (PDAs). The Bluetooth technology relies on short-range radio frequency, and any device that incorporates the technology can communicate as long as it is within the required distance.
Photo: Cables can be a real nuisanceâthat's the problem wireless technologies such as Bluetooth can help to solve. Bluetooth is a similar radio-wave technology, but it's mainly designed for communicating over short distances less than about 10m or 30ft.e're all use to wireless communication by now, even if we don't always realize it. Radio receivers and television sets pick up programs beamed in radio waves hundreds (possibly even thousands) of km/miles through the air.
