If your kids don't care for bath time, then maybe they'd be more excited if the bath water was transformed into full-blown colorful goo! Just pour a packet of H2Goo powder into the water and it soaks up to 400 times its own weight and turns into colorful, safe and non-toxic goo that actually softens the skin. It comes in Red, Pink, Blue, or Green Goo, won't clog pipes and won't stain fixtures, linens, or even the kids. When bath time is over, just pour in the included packet of dissolver powder and it transforms everything back into water. I may have to get some of this for myself.
