How to Blow out Eggs

 

Preserve your artifice
If you plan to display eggs over time, you must hollow them out to avoid creating a science project in addition to your art project.  Here is a simple way to blow the liquid contents out of the raw egg.

SUPPLIES
small straw, ear bulb syringe, or other
  needle-less syringe
straight pin
small bowl
scotch tape
paperclip

 

METHOD
Each type of egg you use will have a different shell.  Some are really thin, making them easy to penetrate with a pin, while others are thicker.  So proceed cautiously.  If your eggshell proves to be delicate and easy to puncture, put a small piece of scotch tape over the area where you will poke the hole, to lessen the likelihood of cracking.

Using a straight pin, poke holes on both the pointy top end of the egg and then on the opposite, larger end.  The top hole (the blow hole) can be the size of the pin, but the bottom hole will need to be a bit larger, as that is where all of the liquid will exit. To enlarge the bottom hole, poke holes around the edges of the original hole, until it widens to approximately 1/8".

Next, break up the yolk inside the egg by opening one end of a paperclip and sticking the straightened wire into the larger hole. Agitate the contents by swirling the clip around inside the shell, being careful not to damage the hole.  This is a very important step, because an intact yolk will not come out of the hole.

Using a short straw placed over the top hole (or a syringe), blow air into the egg, letting the contents drip out of the bottom hole into a bowl.  NOTE: do not blow too hard if air is going in and no contents are coming out.  Your egg might explode from the pressure, causing a dramatic and somewhat messy scene.  We know this from personal experience.  If you are sure the air is going in and nothing is coming out, repeat the paperclip step, with more vigor.  If that doesn’t work, slightly enlarge the holes.

When it feels light with no more liquid, remove any tape and set the shell aside for a moment to rinse and fill your bowl with some water.  If you have a syringe, suck some water up and flush it through the egg, continuing until the water coming out appears clean.  If you don't have a syringe, gently pour water from the faucet into the larger hole, swish it around and then pour it out through the same hole.  Leave your egg shells pointy side up to drip dry, and you are done.
