How to make
To achieve this effect you need bubble wrap.
Wash and clean the eggs. Put them in a suitable container for boiling. Cover them with cold water, add 1 tbsp salt. Boil on low heat for 10-12 min. after boiling point.
Cut open the tubes and drip several drops over the bubble wrap. Don't overdo it because you'd lose the effect.
Put an egg on it and wrap it. You can use several colors at once. You can also dye the eggs the usual way ahead of time and then apply this technique.
