This followup to the how to make plasma in your microwave tutorial, provides us with an easier way to create the effect by using just a single grape — rum and coke optional. Video after the jump.
Plasma typically takes the form of neutral gas-like clouds or charged ion beams, but may also include dust and grains (called dusty plasmas). They are typically formed by heating and ionizing a gas, stripping electrons away from atoms, thereby enabling the positive and negative charges to move freely
