The Pressure Test — How Many Rubber Bands Until It Explodes? An interactive 3D physics experiment built with Three.js and WebGL. Pick from eight realistic fruits, stretch rubber bands around them, and watch them deform, crack, and eventually explode under pressure. Choose Your Fruit Watermelon — the classic green striped specimen Pumpkin — ribbed and orange, satisfying to squash Cantaloupe — netted skin with green sutures Durian — spiky and tough Grapefruit — citrus with oil-gland dimples Coconut — tender green with water droplets Pineapple — diamond-scaled skin under a tall spiky crown Pomegranate — glossy crimson rind packed with ruby arils How It Works Tap or click the fruit to add a rubber band. Each band tightens and increases pressure. The fruit deforms in real-time — you'll see it pinch at the waist, bulge at the ends, and develop surface cracks. Keep adding bands until it explodes!
