Sun Stove — Solar Rice Cooker Lab
Build a panel, box, or parabolic solar cooker in 3D, aim it at a sun placed by real solar geometry, and ray-trace how much light actually lands on the pot. Then simulate the whole day: the temperature curve, when the water hits 95°C, and whether the rice is done before sunset — with concrete upgrade advice when it isn’t.
Boy Kibble Lesson Track
Use the Learn with Fizz track for short lessons on the formula, healthier upgrades, protein, sauces, shopping, meal prep, and backup meals.
