It takes about 4 to 7 days. Put an egg in a cup and fill it with apple cider vinegar till egg is covered. Cover tightly n let it sit. Each day give it a swirl. At the end u rinse off the egg n VIOLA! A rubber egg! Just be careful...it will bounce but is still delicate. And very smelly when it breaks. LOL ...Not rotten -- just smells like vinegar. Always keep it in the fridge during the whole process too. If you place the "naked egg" in corn syrup, it will shrink/shrivel up. The vinegar inside the egg moves through the semi-permeable membrane. You can then place it in water with food coloring and "color" the inside of the egg and it will fill up again due to osmosis
