bigclivedotcom | Orbeez can be dehydrated by brine @bigclivedotcom | Uploaded 1 month ago | Updated 4 hours ago
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.
