Challenge: Make a Smoke Generator

Objective

Students will build a functional smoke generator using natural materials. The challenge encourages innovation and resourcefulness, with the practical application of creating smoke for signaling, deterring insects, or other survival needs.

---

Materials Needed

Natural Materials:

• Wood: Dry, easily combustible wood (such as pine, fir, or cedar).
• Leaves, Grass, or Moss: Dry, fibrous material to help create smoke.
• Bark: Large pieces of bark that can be used as a covering for the generator.
• Stones: A few stones to act as a base or weight to stabilize the structure.

Tools:

• Knife (for cutting and shaping wood).
• Fire-starting tools: Matches, fire steel, or flint and steel (optional for igniting the fire).
• Axe or hatchet (if available, for cutting larger logs).

Safety Gear:

• Gloves for handling sharp tools and fire materials.
• Water or a fire extinguisher for safety when working with fire.

Preparation

1. Set Up the Challenge Area:
   • Find a safe area where students can build and safely burn a small fire.
   • Make sure to provide enough space for multiple teams to work without interfering with each other.
   • Have a clear area for storing water or fire-extinguishing materials.
2. Teach Basic Fire Safety:
   • Review safety rules for working with fire and tools.
   • Emphasize the importance of control and supervision when creating smoke.
3. Demonstrate:
   • Show examples of smoke generators and explain their function, such as their use for signaling or repelling insects in a survival situation.

Instructions

Step 1: Create a Fire Pit Base

1. Gather Stones:
   • Arrange stones to form a small, safe fire pit for your smoke generator. This will act as the foundation to contain the fire and smoke.

Step 2: Construct the Smoke Generator Structure

1. Build a Base Layer:
   • Use dry, small twigs, sticks, and other easily combustible materials to form the base of your smoke generator. This layer will help get the fire going.
2. Add Fuel:
   • On top of your base layer, place slightly larger twigs or small branches. Leave enough space for air circulation to encourage the fire to smolder rather than burn too hot.
3. Create the Smoke Chamber:
   • Use larger, dry sticks or logs to form a partially enclosed space. The goal is to trap the smoke, not the heat, allowing it to rise in a controlled manner.
   • You can use bark or large leaves to cover parts of the structure, ensuring the smoke stays contained but escapes through a small opening at the top.

Step 3: Add Smoke-Producing Materials

1. Layer Materials:
   • Add dry moss, grass, or leaves into the smoke chamber. These materials will create thick smoke when ignited. You can also add small amounts of wet, fibrous plant material for more consistent smoke.
2. Create Ventilation:
   • Ensure there is enough airflow into the base to encourage smoldering. If the smoke is not dense enough, increase airflow by adjusting the arrangement of your fuel or adding more dry, fibrous material.

Step 4: Ignite the Fire

1. Light the Base Layer:
   • Start the fire by lighting the base layer of twigs and branches. You can use matches, flint and steel, or a fire starter.
   • Allow the fire to catch and begin smoldering.
2. Maintain the Fire:
   • Once the fire is burning, monitor it to ensure it produces thick smoke without flaring up into a large, hot flame.
   • Add additional materials (like damp moss or leaves) to increase the smoke output if necessary.

Step 5: Test and Adjust the Smoke

• Observe the smoke output. If there’s not enough smoke, add more fibrous material or adjust the airflow. If the smoke is too light, check for gaps in the structure where air is escaping, and block them.
• Once you have a steady, thick smoke output, the generator is complete.

Challenge Variations

1. Team Competition: Who can build the most effective smoke generator in a set time?
2. Survival Scenario: Have students create their smoke generator as part of a larger survival scenario, where the smoke is used to signal help or repel pests.
3. Efficiency Test: Measure which smoke generator produces the most smoke with the least fuel.
4. Long-Term Smoke: Test which design can create continuous smoke over a longer period, simulating long-term survival needs.

Debrief and Reflection

1. What Worked Well:
   • Discuss the best materials and techniques for creating dense, consistent smoke.
2. Challenges:
   • Reflect on difficulties faced, such as insufficient airflow or materials that burned too quickly.
3. Real-World Application:
   • Discuss how a smoke generator could be used for survival signaling, insect control, or fire starting.

This survival challenge provides an excellent opportunity for Acton Academy students to practice problem-solving, collaboration, and hands-on bushcraft skills. By creating a smoke generator, students learn the importance of resourcefulness, fire safety, and practical survival techniques that could be applied in real-life situations.
