Microbot
Official Question Material
Prep: 30-40 Seconds
Each tube shaped microbot is a sandwich of three materials. A graphene outer layer, which binds to heavy metals. A middle layer of nickel gives the bots magnetic polarity, so they can be pulled through wastewater with magnets. Platinum inside for propulsion. Just add a bit of peroxide to the wastewater, and it will react with the platinum to form water and oxygen bubbles, which propel the tubes along.
