Voltaic batteries of all shapes and sizes are objects that convert chemical energy into electrical energy. You probably use batteries to power your cell phone, iPod, or any number of wireless gadgets. But did you know that you can actually use chemical energy stored within a lemon to power a small LED light? It\'s true, and we\'ll show you exactly how in the Fruit-Power Battery experiment. How does it work? Batteries are comprised of two different metals suspended in an acidic solution. With the Fruit-Power Battery, the two metals are zinc and copper. The zinc is in the galvanization of the nail, and the penny is actually copper-plated zinc. The acid comes from the citric acid inside the lemon. The two metal components are electrodes, the parts of a battery where electrical current enters and leaves the battery. With a zinc and copper set-up, the current will flow out of the penny and into the nail. The electricity also passes through the acidic solution inside the lemon. Once the Fruit-Power Battery is connected to the LED, you create a complete circuit. As the electrical current passes through the LED, it lights the LED, and passes back through all of the lemons.

The topic of knowledge can be widely found within Islamic teachings and practices; So much so that the first commandment and revelation from Allah (SWT) to his messenger prophet Muhammad (PBUH) was \"Read, In the Name of your Lord who has created all\".
Narrations from the Prophet (PBUH) tell us of the high statuses in which knowledge seekers are rewarded and over 700 verses within the Quran speak of \'knowledge\' and its associated words.
But in a world occupied by continuously developing technology, mankind has become both reliant on these gadgets and distracted from seeking Islamic knowledge.
At the same time Muslims in the Western world are too preoccupied with developing open societies to seek knowledge of Islam.
This week\'s Islam and Life asks: What importance does Islam place on seeking knowledge?
