Okay. Equipment: human, refrigerated bantam egg, fresh bantam egg, store egg. outdoors So I wanted to see which were tougher. I threw the eggs into the air, trying to keep the same distance,speed. They all made it. I threw them about 20 feet, STORE EGG CRACKED. Threw 30 feet and out with store egg. Both bantam eggs are good, just dirty. Threw them from one side of the house (lengthwise) to other. Refrigerated egg broke!!!! So I spent 20 minutes throwing the other one and finally pitched it like a softball and hit the basketball goal. Sooooooo I think non refridgerated are stronger.
