Blow out eggs with a syringe
It is even easier to "blow out" Easter eggs by means of a syringe. With the injection cannula drill a hole in the egg, then enlarge the hole slightly (with a small drill, small Phillips screwdriver o. The like). Now fill the syringe with air, pierce the previously made hole in the egg, and inject the air with the syringe into the egg. This increases the internal pressure in the egg, and the liquid spouts out.
Poke something with a roulade needle in the egg, so that the liquid can escape from the hole more easily.
