High water absorption polymer balls (sometimes referred to as the brand Orbeez) are beads of sodium polyacrylate that absorb huge amounts of water.
While experimenting with getting neutral buoyancy for a moving flow of balls in a heated bottle, I discovered that adding salt to the water actually resulted in the balls being dehydrated again.
I wonder if this effect has any practical engineering application.
