 * POTATO VS. EGGSHELL**

//**Question**// Which will prove to be stronger: potato hollowed out to 1/4 of a cm or eggshells?

//**Hypothesis**// I believe that the 1/4 of 1 cm hollowed potatoes are going to be stronger because they are thicker then the eggshells.

//**Results**// Four eggshells halves can hold approximately 4lbs. Four hollowed potato halves con hold approximately 24 lbs. A huge different!

//**Conclusion**// I think that it is impressive that the tiny, delicate eggshell can hold the four lbs. of book. I was sure that the potatoes would hold more weight because it just makes sense. Even hollowed out to 1/4 of 1 cm, they are still quite a bit bigger then the skinny eggshells. I did not expect them to hold that much though. I concluded that the inner core of the potato is a strong substance.

//**Questions for further study**// If I was doing this experiment again, I would probably put the same book on the potatoes and on the eggs and then wait a minute and then put more books on and wait another, and wait. I'd let it sit there for a while to see if that made a different effect. I would also not just put books on the eggs and the potatoes, I would put bags of food that said how much it weighted. I also might use a different egg.
