My 6 year old son's favorite show is myth busters. So, we decided to to test a myth of our own. Do bad eggs sink in water? Well, we can tell you that fresh eggs float and that an egg left on the counter for over 4 weeks finally started to bob in the water a little. We don't have an old enough egg to see if it really floats yet. As we all know, fresh eggs last so much longer anyway when you don't wash them and all of that. So happy to be joining this forum. You guys are really funny and in such a wholesome way!
