What is "bindeez"

Bindeez (also marketed as Aqua Dots, Beados, and Pixos) are a children's toy. It was subject to a multi-national product recall after it was found that the Wangqi Product Factory in Shenzhen, China had used a cheap chemical that was a pharmacologically active sedative prodrug instead of the safer specified one in some shipped toys, resulting in the illness and hospitalization of some children who ingested the beads.
