Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...

Casein is a protein that is found in milk. Groups of casein normally float around in milk without bonding. These groupings have a negative charge. The acidity of the Red Bull causes the negative charges on the casein groupings to become neutralized. Instead of pushing each other apart, the casein starts to clump together causing the milk to curdle and form solid matter.

You must watch it yourself to see the changes happen within a cell when you make some changes.
This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many de...

Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.
