Magnetact Animals are magnetic sheet-based kinetic toys. With the global COVID-19 pandemic that began in early 2020, it has become difficult to hold workshops that bring people together in one place. So, we designed a kinetic toy kit that can be sent in an envelope, be constructed with ease, and work without any batteries. The kinetic toy, constructed using magnetic sheets, cardboard, and paper, allows the users to design and create "animals" with variable motions. At the two online workshops we held for 15 participants from 3 to 11 years old, all of the participants enjoyed building toys and some invented original mechanisms and new animals.
