how many pounds of pressure does it take to crack a walnut?

Question

if applicable, provide source for answer.

Answer 1

I think not too many.I smashed the walnut in a very hard surface with the palm of my hand.It works every time. I'm a not big guy,and my pressure is enough to break the dry fruit.

Answer 2

It depends on the type of walnut. If it's an English Walnut, those can be open quite easily. If it's a Black Walnut, get out the heavy equipment. It's recommended to place the Black Walnuts on a blacktop drive way, and run over them with your car.

I can tell you, the car method doesn't always work though. Usually I put them into a vice on my husband's workbench and crack into them that way.

Answer 3

Not alot I don't think...my dad used to open them by pressing them in between the heels of his hands somehow. Similar to not breaking a raw egg when you apply pressure while holdind it long ways.
