Valerie Casasanto, outreach manager for the Ice, Cloud, and land Elevation Satellite-2, or ICESat-2, demonstrates the "Motion in the Ocean" water density activity. The materials needed are tennis ball tubes, a tub or container for excess water, salt, food coloring, tubing or a clear straw (a disassembled pen body could also work), and high density foam (such as from a children's puzzle floor mat) to make the fluid separator plugs.
