Science Fair Question11/22/2004 |
Hello. I am a seventh grader doing a Science Fair Project. I e-mailed you a couple of days ago and I received your message. Thank you. You helped me. But, I have another question. I am testing with hard-boiled eggs and then I am letting them dry then I am putting them in different liquids to soak. I am then going to let them dry and brush each egg with a toothpaste. (I am only using 6 different toothpastes) I am not sure of how long to let the eggs soak in the liquids. If you could e-mail me back soon woth an answer, that would be GREAT!!! Thanks SOOOO much!
I would soak them for at least a week.
