Well, I was hoping someone had tried something along these lines. From what I've read, vinegar takes about a week to work.
For anyone who cares to know, the point of this activity is to be the end of an eggbreak project, in which as many steps as possible are used to break an egg. Example: I press a switch, which turns on a fan, which blows over a balanced knife, which hits a string which was holding up a weight, which then falls onto the egg.
Of course, this project has been done at my school for many years, and I hope to do something cooler than most, as most ideas have already been used. Thus, instead of flinging, smashing, or piercing an egg, I intend to rapidly dissolve it.
So, I was hoping someone here might be able to show a formula or something showing the correlation between the concentration and speed of dissolving. Guess I'll just have to try it.
