Ice Fishing

Paint a plate with materials and watch 👀 heat spread across it in real time ⏱️. Ice Fishing is a heat-flow lab for your phone 📱. Paint a square plate with different materials, set a hot side and a cold side, and watch 👀 the temperature spread across it. Pick copper, aluminium, steel, concrete 🧱, granite, glass, water gel, oak, still air or foam. Drag ✋ across the plate to lay the material down. Heat moves fast ⚡ through copper and slowly through foam, and you see 👀 the difference as it happens. Colour bands and contour lines show where the heat has reached. What you can do in Ice Fishing: - Paint materials onto the plate with an adjustable brush. - Place hot sources and cold sinks, or unfix a cell again. - Place probes on the plate and read their live temperatures. - Follow the equilibrium percentage and the estimated time ⏱️ to steady state on the Desk. - Load one of eight ready-made plates, such as Copper Spreader, Heat-Sink Fin, Cold Bridge and Thermal Maze. - Save 💾 your own plates and keep a log 📝 of every run. When a plate settles, the run is logged. Open its report 🧾 to see 👀 probe temperature curves, how the temperature distribution changes over time ⏱️, and a heat budget 💰 that shows what flows in and what flows out. The Materials tab lists each material with its thermal diffusivity. Open one to see 👀 its conductivity, density and specific heat, and a chart 📊 of how a pulse of heat spreads through it over time ⏱️. You can also add up to three materials of your own. Ice Fishing suits students, teachers, engineers and anyone curious about how heat moves through different materials.
