Picture this: a rocket‑shaped coffee pot, steam swirling into the warp bubble, the nozzle spitting out espresso instead of ionized plasma. The handle doubles as a lever that toggles between “brew” and “warp.” I drew it on a napkin last night, added a tiny galaxy swirl in the froth—makes the coffee feel like a star. If you need a quick doodle, just grab any paper, sketch a rocket, put a coffee mug inside, and let the steam form a swirling vortex. Voilà, warp‑coffee ready!

Alright, let’s do a quick heat‑diffusion demo in plain Python so you can eyeball the espresso staying hot while the warp bubble hums. No fancy packages—just NumPy and a tiny explicit scheme. Grab a 3‑D array for temperature, set the warp bubble as a moving heat source, and step the diffusion equation forward. Here’s the skeleton: ```python import numpy as np # Grid parameters nx, ny, nz = 30, 30, 30 # small grid, tweak for more detail dx = dy = dz = 0.01 # metres dt = 0.0005 # seconds – keep small for stability alpha = 1.4e-7 # thermal diffusivity of espresso (approx) steps = 2000 # number of time steps # Initialise temperature field T = np.full((nx, ny, nz), 20.0) # room temp, C # Place coffee pot at centre cx, cy, cz = nx//2, ny//2, nz//2 T[cx-2:cx+3, cy-2:cy+3, cz-2:cz+3] = 90.0 # coffee core, C # Warp bubble: a moving hot spot that keeps the coffee hot def warp_bubble(t): # simple sinusoidal motion in x x = int(cx + 5*np.sin(0.01*t)) return (x, cy, cz) # Laplacian helper (simple 7‑point stencil) def laplacian(U): return ( np.roll(U, 1, axis=0) + np.roll(U, -1, axis=0) + np.roll(U, 1, axis=1) + np.roll(U, -1, axis=1) + np.roll(U, 1, axis=2) + np.roll(U, -1, axis=2) - 6*U ) / dx**2 # Main loop for step in range(steps): t = step*dt # Update warp bubble heat source wx, wy, wz = warp_bubble(t) T[wx-1:wx+2, wy-1:wy+2, wz-1:wz+2] = 90.0 # keep that core hot # Explicit diffusion step dT = alpha * laplacian(T) T += dt * dT # Optional: print average coffee temp every 200 steps if step % 200 == 0: coffee_region = T[cx-2:cx+3, cy-2:cy+3, cz-2:cz+3] print(f"Step {step}, avg coffee temp: {coffee_region.mean():.2f}°C") ``` Run that, and you’ll see the coffee core stay around 90 °C while the warp bubble sweeps around, stirring the whole pot. You can tweak `alpha`, the bubble motion, or even add a convection term if you want that latte foam swirling. Once you’ve got the numbers, feed them into your render engine and adjust the nozzle angle until that espresso density is just right. Happy warp‑brewing!

Sounds like a plan—just fire up the script, grab a coffee, and let the warp bubble do its thing. If the core starts sweating, crank that bubble up or tweak the diffusivity in the code. Once the numbers are chill, you can hit render and tweak the nozzle until the espresso explodes like a star. Let me know if you hit any hiccups!
