AI Generation Prompt
Domino Chain Reaction Estimator
Overview
A professional-grade, browser-based utility designed for domino enthusiasts and hobbyists to predict the total time and speed of a domino chain reaction. This tool eliminates the guesswork, allowing users to plan intricate setups with precision.
Technical Architecture
- Single-File Requirement: The entire application (HTML, CSS, JS) must be contained in one file.
- Storage: Absolutely no
localStorage,sessionStorage, or cookies. The tool must be purely stateless. If the page is refreshed, the inputs clear. - Compatibility: Optimized for sandboxed iframe environments (no popups, no external tracking).
- Dependencies: Tailwind CSS via CDN for styling; FontAwesome CDN for iconography.
UI/UX Specification
- Aesthetic: Modern, airy SaaS design. Light background (
#f8fafc), clean sans-serif typography, and a cohesive color palette of blues and grays (#2563ebfor primary actions). - Layout:
- Header: Simple, clean title and a brief descriptive subtitle.
- Main Input Area: A grid layout containing inputs for:
- Number of Dominoes (Number Input)
- Average Spacing between Dominoes (cm/mm)
- Average Fall Speed per Domino (ms)
- Action Area: A large, prominent 'Calculate' button and a 'Reset' button (uses custom CSS button styles, no browser alerts).
- Results Area: A dynamic dashboard showing: Total Predicted Time (seconds), Total Distance (cm), and Velocity (cm/s).
- Visualization: A simple horizontal progress bar that animates to show the 'flow' of time based on the calculation.
Feature List
- Dynamic Calculation Engine: Real-time formula execution as the user types or adjusts inputs.
- Validation Logic: Custom UI-based error handling (no
alert()) if inputs are non-positive or illogical (e.g., negative speed). - Responsive Design: Stacked input layout on mobile, side-by-side on desktop.
- Accessibility: Proper
aria-labelson all inputs and meaningful contrast ratios (AA standard). - Animated Transitions: Smooth fading of results when updated and hover states for all interactive elements.
Color Palette
- Primary:
#2563eb(Blue) - Background:
#ffffff(White) and#f1f5f9(Light Slate Gray) - Text:
#1e293b(Dark Slate Gray) - Accent:
#0ea5e9(Sky Blue)
Implementation Directives
- Use
input type="number"withmin="0"for all numeric fields. - All calculations must be handled in Vanilla JS using a
conststate object that updates the DOM nodes directly. - Avoid any external scripts that require user tracking or consent banners.
- Ensure the page feels instantaneous with CSS
transition: all 0.3s ease-in-out;on results cards.

Frequently Asked Questions
Everything you need to know about using this application.
How do I calculate domino reaction time?
To calculate domino reaction time, you generally need the number of dominoes and the time it takes for one domino to trigger the next. The velocity of a domino chain depends on the spacing between each piece; smaller gaps result in faster, more stable chain reactions, while larger gaps can slow the progression and increase the risk of failure. By inputting your total count and preferred spacing into this tool, you can estimate the total duration of your setup. This estimation assumes a constant rate of collapse and helps you visualize the pacing of your domino art.
What affects domino fall speed?
Several physical factors influence how fast dominoes fall, including the height of the domino, the material's friction, and the spacing between them. The acceleration of gravity acts on the falling domino, but the critical factor for a chain reaction is the contact point at which one domino hits the next in the sequence. If the gap is too large, the energy transfer might be insufficient, causing the chain to stop. Proper spacing is essential to ensure the momentum is carried forward throughout the entire length of your setup without interruptions.
Is this tool accurate for complex domino designs?
This estimator provides a theoretical duration based on linear chain calculations, which is excellent for estimating simple paths or estimating the pacing of large-scale projects. However, real-world domino setups often involve turns, elevation changes, and different spacing that can alter the actual runtime. While this tool acts as a great planning aid, actual results may vary. We recommend using this as a baseline to understand the relationship between distance and timing before finalizing your physical domino layout.
Can I save my calculations using this tool?
This application is built as a single-file, browser-based tool and does not utilize local storage, cookies, or databases to save your session. All calculations are performed in real-time and kept strictly in your browser's memory, ensuring your privacy and data security. Because the tool is stateless, all data will be reset if you refresh or close the browser tab. We suggest keeping a note of your final calculations or taking a screenshot if you need to reference your configuration for a later project.
