Egg Project
What happens when you soak a egg with vinegar then put it in 300 ml grams of water and 100 ml grams of corn starch?
After completing this project we could see that the vinegar had a effect on the egg, it ate away at the shell of the egg. Making this very fragile and changed the texture of it. After soaking the egg in water and corn starch we confirmed that there was a 95 percent confidence that the solution changed the egg. The more corn starch you had in the water the more it took water from the egg and shrunk. With more water in the solution the egg swelled.
