An egg piercer is a kitchen tool that is used to break a tiny opening in an egg shell to prevent the shell from cracking and the yolk from turning green while boiling. This tool is typically a sharp steel pin that is housed inside a base and that protrudes only when an egg is pressed onto it. An egg piercer also can be used to prepare egg shells for crafts.
The base of an egg piercer typically is spring-loaded, so when the operator presses the egg down on the egg piercer, the needle will pop up and poke a tiny hole into the shell. An egg piercer can come in a variety of shapes, sizes and colors to fit any kitchen décor.
Some people enjoy decorating empty egg shells. This delicate craft requires the removal if the insides of an egg without breaking the shell. An egg piercer is perfect for the job. Two holes are needed, one at each end of the egg. The crafter can then blow the insides of the egg carefully through the egg piercer hole by blowing into the larger end of the egg. Once all the contents of the egg have been removed, the egg shell can be decorated.
