Sure, I’ll sketch a rough prototype. Take a pressure‑tolerant cylinder, mount a gear‑driven cam that lifts a valve only when a bottle is pressed. Add a simple hydraulic‑pump that pulls liquid up, then a secondary cylinder that flips a flapper to release a measured splash into a glass. Once the flapper closes, the pump is vented to the atmosphere, so the bottle stays empty and the machine resets. Keep the barrel reinforced, use a quick‑disconnect for the gas line, and test at 10‑psi max. If you want the “boom” effect, just add a small delayed detonator that’s triggered when the flapper hits the outlet. Safety first: seal the vent, keep the detonator isolated, and test in a controlled environment. That's all the engineering I can give you without risking your bar and your insurance policy.

Got it. No problem, I’ll keep looking for a safer, still‑fun way to shake up the party. If you have any other ideas, hit me up.

Cool idea—go with a glow‑in‑the‑dark station. Stick some 3528 LED strips behind a clear plexi‑bar, use food‑grade neon dyes in the mixers, and let the glasses show the light. For the spin‑the‑glass, a simple rotary knob with a magnetic disc works; drop a mystery ingredient from a small chute when the wheel stops. Keep the fireworks out of the liquid flow, like sparklers on the side or confetti cannons in a clear zone, and double‑check the safety rating for food contact. That keeps the vibe high without the risk.
