A hands-on session aiming at exploring low cost to no cost multidisciplinary practices that connect environmental education and tinkering and making. Participants will be encouraged to connect with materials they engage with daily, re-interpret them, work with them and investigate the potential of moving from a “saving stuff for just in case” mode to a “purposeful investment” mode. We will be trying some alternatives for the usual material in tinkerers’ stock, like hand craft and art supplies, and building material with things like fused plastic or cardboard and explore the potential they offer in emphasizing tinkering practices. Classic tinkering activities like circuit explorations, linkages and gears will be hacked with recycled material. We will also investigate recycling as a tinkering practice in itself. CD drivers, dolls, Christmas lights and other stuff will be used to recreate and design personalised dolls, remote control cars, generators and operation games. We will reflect on the experience, considering practicality, challenges and advantages.
