First thing to do is grow the water beads.(most come small and have to sit in water to grow)
Then in a bin add water, some baking soda, epsom salt, lavender oil and the water beads.
Make sure to have a hand towel ready to wipe off feet before letting kid/kids run around.
My daughter found this so fun, she loved feeling the beads in the water and was even catching them between her toes.
Once we were done I emptied the water, put fresh water in and let the beads sit for play at another day.
