Based upon the method of making recycled paper and the knowledge of natural pigments, this popular science experiment proposed an approach for making recycled paper dyed with vegetable pigment. This popular science experiment exhibited scientific, intriguing, brief and high operability. Moreover, we also creatively designed some interesting handmade works including pulp paintings, coasters, and origami, using dyeing paper and dyeing pulp. This experiment would provide a useful practice of chemical sustainable development, which helps the public better understand the chemical principle of recycled paper making and the extraction method of natural pigments.

Key words: Making of recycled paper, Vegetable pigment, Science popularization experiment
