Lyrics:

Little ball, banana pear, Malan flowers bloom for twenty-one;

"Malan Blossoms Twenty-one" is a song that children will sing when they play bungee jumping.

bungee jumping, also known as bungee jumping, bungee jumping and monkey bungee jumping, is a folk game suitable for children, which was popular from 195s to 198s.

the rubber band is an elastic string made of rubber, about 3 meters long. After the rubber band is straightened and fixed, it can jump back and forth. Three to five people can play together, or they can compete in two groups. It is very interesting to dance and sing. First, two people each take one end to stretch the rubber band, others take turns to jump, and act according to the regulations. The winner wins. If the rubber band is wrong or not hooked halfway, another person will jump.
