What liquids can kill a lima bean?

I have heard that Orange Juice kills lima beans. I am not sure about vinegar, i heard that it does. I am about to do a science fair project. That is one of the liquids that i am using. So i hope it doesing but it might. Other liquids may also kill lima beans. It is hard to tell witch. You can only use so many liquids in different tests and projects. =)
