Which are the toys which you have made/played during childhood which produces sound? It will be nice if you can also sketch it on paper and share the picture.
I am remembering of making a sound using thumb and ring finger.
Whistle, toy drum, and a paper “bujrst” sound maker
Drumming on the school benches is something I found the kids I used to teach do!
Also, blade inserted in the bench to vibrate!
