Bizarre travelling flame discovery

Tutorial: Creating Bizarre Travelling Flames with Lighter Fluid

Step 1: Understanding the Concept

1. In the video, Steve Mould pours lighter fluid into a ring-shaped trough and sets it on fire, creating a flame that travels round and round the ring.
2. The phenomenon is explained as an example of an excitable medium, where the lighter fluid vapor ignites in a continuous loop due to the evaporation and reignition process.
3. The key parameters for creating the spinning flames include the width of the trough, the size of the opening, and the design of the ring.

Step 2: Designing the Trough

1. Download a parameterized CAD file from a designer like Oscar Morris to customize the trough dimensions.
2. Experiment with different trough widths and opening sizes to find the optimal configuration for the flame to travel smoothly.
3. Aim for a trough width of around five millimeters with a semi-circular cross-section for best results.

Step 3: Setting Up the Experiment

1. Pour a thin layer of lighter fluid into the trough to create a ring of vapor above the liquid.
2. Ensure the opening of the trough is pointing slightly inwards for better flame propagation.
3. Use caution when handling lighter fluid and ensure safety measures are in place.

Step 4: Igniting the Flames

1. Light the vapor ring at one point to initiate the flame's journey around the ring.
2. Observe the flame as it travels around, fueled by the continuous evaporation and ignition of the lighter fluid.
3. Experiment with different designs, such as splitting the ring or adding junctions, to create varied flame patterns.

Step 5: Understanding Excitable Mediums

1. Learn about excitable mediums and how they switch to an excited state, leading to interesting movements and patterns.
2. Explore examples of excitable mediums in nature, such as heart fibrillation or Mexican waves in sports stadiums.
3. Consider the concept of excitable mediums in the context of the spinning flames created with lighter fluid.

Step 6: Safety Precautions and Further Exploration

1. Remember that working with lighter fluid can be dangerous, so handle it responsibly and under adult supervision.
2. If interested in creating similar designs or experimenting with excitable mediums, reach out to designers or share ideas with the community.
3. Stay curious and explore the possibilities of excitable mediums in creating unique and mesmerizing visual effects.

By following these steps, you can create your own version of the spinning flames experiment using lighter fluid and explore the fascinating world of excitable mediums. Remember to prioritize safety and enjoy the process of discovery and experimentation.
