Whizzy Dizzies have been a favorite toy for generations. You sit on the seat and turn the wheel on the top (which is great exercise and builds hand-eye coordination) and you spin. Today’s Whizzy Dizzy toys are oversized to fit two children (cause fun is always better with a friend) and made of heavy-duty plastic. Most can be used indoors or out. They are great for kids 3 years or older.
