What do you when egg whites beat up?

Egg whites beaten up to the correct stage become stiff peaks. When an egg white is beaten up, the proteins in the egg white will form a network of bonds with each other. This network is what gives egg whites their structure and makes them foamy. The more you beat the egg whites, the stronger the network of bonds will become and the stiffer the peaks will be. When the egg whites reach the correct stage, they will hold their shape even when you turn the bowl upside down.
