How do you separate salt and pepper from sand?
I can only use a small cup,pie tin,funnel,comb,felt,spoon,coffee filter,measuring cup,and 2 index cards.Please help!! !!!! How do i separate it all i tried running the comb through my hair and putting it over the pepper to create static electricity but it didn’t work.I am allowed to a create an object that will separate it but i can only use the items above.
Put it in water to dissolve the salt, and the pepper will float to the top. Skim off the pepper, and evaporate off the water to crystalize the salt.
Can you use water? Salt is the only thing that dissolves in water, so if you run the mixture through the filter and then boil it, you will get pure salt.
Maybe your hair didn’t generate enough static. Try rubbing it against wool or cat fur for a long time.
