Rubber Band Can Be Formed

About Rubber Band Can Be Formed Android App

This is a traditional art, well.. Not really traditional.. Using rubber band to form shapes- by twisting, pull,etc. Children usually like this art, because it's simple and easy. This art is different with the Ayatori art, Ayatori arts are using strings not rubber bands. This is really popular in Indonesian school, most of children usually can make this art.
Of course! Rubber Bands! I suggest not to use new rubber band, because it's really hard to stretch it. Used rubber band will easier to stretch
