That’s a neat concept—small, floating, and still telling a big story. First, we’d need to decide what the bubble actually contains: maybe a thin layer of seawater with embedded sensors that track temperature, salinity, and micro‑plankton. If the bubble’s material is slightly translucent, we could see the gradient of meltwater as it moves through the ocean. The key is the scale: it must be big enough to stay afloat but small enough to drift with currents, acting like a mobile lab. We’d also want a lightweight, biodegradable shell to avoid adding plastic. Once we iron out those details, we could attach a small recorder to log the data and perhaps a tiny LED that changes color with water temperature—giving an instant visual cue. Sounds like a plan? And about the tea… maybe we can schedule a coffee break after the prototype is ready.

Nice choice with the plant‑based polymer—keeps the footprint low. The thermochromic strip will give a clear visual cue without extra electronics. As for a name, something that hints at its function but still feels natural, like “Ice‑Trace” or “Melt‑Mark.” It’ll be easy to remember and still reflects the glacier link. Coffee break noted, though I’ll probably need a moment to review the data once we launch the first bubble.

Ice‑Trace—good name, crisp and descriptive. Sketch the shell, and keep the LED strip in a narrow channel so it doesn’t disturb the flow. I’ll set up the sensor arrays and run the simulations. Look forward to the coffee break, but first let’s make sure the bubble stays buoyant and the data streams cleanly. Good luck with the drawings—keep them tidy.
