The crystals will absorb the water and turn into a gel like substance.
Now, SpinMaster makes this concept a fun science experiment for kids. This Umagine Squishy Baff turns ordinary water into glorious colorful goo and then back again. My daughter loved squishing the goo between her fingers! The kit comes with enough Squishy Baff powder to make two baths of goo! It’s safe, fun, and doesn’t leave stains or residue. When you are done playing, simply add the dissolving powder and watch it go down the drain! Transform water into fun with Squishy Baff! Non-toxic, biodegradable and easily goes down the drain.
We never used it for a bath but we had fun making a few batches to play in.
It was fun and easy to do. I can imagine putting into the bath would be exciting and probably very messy, so we stuck to just keeping it in a large bowl to play with. Also the dissolving packet did bring the goo back to a liquid state but not completely.
