This reasonably large ball can be rolled and thrown and makes an appealing giggling sound. It is guaranteed to attract attention. Another toy which is extremely popular, because of its silly sound, is the groan hammer. Just shaking this plastic hammer produces a very audible groan. For those who can hit keys with fingers, fists or sticks xylophones, glockenspiels, and keyboards are great.
Guitars provide a nice musical response for little effort.
Maracas, jingle bells, castanets are all very responsive instruments. For those with less ability musical tapes are great. The very jiggly sounds of many musicians specialising in children's music has much appeal. Older children and young adults will have favourite types of music or artists. Parents will know these and can experiment too.
