Here's the same Home Demo in convenient PDF form!
This is a great experiment to demonstrate density. I have demonstrated it to my classes with whole eggs (still in the shell), it tends to be easier (less messy) and still provides a good visual demonstration. The Nye Labs.com PDF file looks like it has information from a different lab in the "What's happening?" section but it is correct in the top section of this tutorial. Thanks for the idea.
I heard that you can tell if an egg is spoiled by tossing it in tapwater and seeing if it floats. As you noted, the egg should sink in tapwater. So if it floats in tapwater, it's no good to eat. What's the reason behind this? I think it has to do with the spoiled egg being more gaseous, but I'm not 100% sure.
