I'm making a trip back home (to the coast) shortly, and I would like to bring back sand from the beach with me as a keepsake or memento. It's just a short weekend trip, and I won't be checking any luggage, so I was wondering if it's even worth bothering trying to bring sand aboard the plane in my carry-on?
If so, what can I do to make the security screening as smooth as possible? I was planning on putting the sand in sandwich-sized plastic bags, enclosed in a larger quart- or gallon-sized bag.
