Water Beads Foot Spa Same effect as the one advertised on TV, but much cheaper. Grow the water beads in a dollar store dish pan overnight. (Water beads are available for $2 in the floral section at Walmart - I used two packs.). Remove excess cold water, and add warm water when ready to use. I also added one tbsp of bleach which will sanitize approximately 12 cups of water. The girls love the sensory experience, and I love the price :)
