Add sand into a container such as a plastic zip-lock bag, water bottle, vile, small glass jar or other decorative plastic or glass containers that has a sealed lid.
Add different colored sands from several beaches to create sand art. To do this, it may be best to collect sand from beaches and store them in plastic bags until you are ready to complete the project, prior to leaving Hawaii.
Seal container with the sand in it, tightly and pack in your checked baggage. It may be a good idea to place the container in a separate sealed plastic bag to prevent sand from leaking. Be aware that the inspectors at the airport will more than likely open your luggage, to ensure that that it is only sand and not a potentially harmful substance.
