Make plasma with grapes in the microwave
This video demonstrates how a plasma can be made from heating a grape in a microwave. When gases from the grape absorb microwave energy electrons are removed. The free-moving electrons and positively charged gas molecules form the plasma. The experiment shows how plasma produces visible light. However, the explanation is limited.
