Kavi's Material Hunt
Kavi picks up a glass 🥛, a wooden spoon 🥄, a rubber band and a metal key 🔑. "Each one feels so different!" says Kavi. "Some are hard, some bend, some are see-through, and some keep water out." Kavi grins. "Let's compare materials by what they can do — and pick the best one for each job!"
