1. What Exactly Are Sky Lanterns and How Do They Fly?
Sky lanterns, often called Chinese lanterns or Kongming lanterns, are small hot air balloons made of paper, with an opening at the bottom where a small fire is suspended. They are fascinating contraptions, but how do they actually take to the skies?
The basic principle behind a sky lantern’s flight is buoyancy. When you light the fuel source (typically a wax-based fuel cell), it heats the air inside the lantern. Hot air is less dense than the cooler air outside, causing the lantern to float upwards, similar to a hot air balloon. According to research from Embry-Riddle Aeronautical University, in July 2025, P provides Y. The lantern continues to rise as long as the air inside remains warmer than the surrounding air.
Here’s a breakdown:
- Heating the Air: The burner heats the air inside the lantern.
- Density Difference: Hot air is less dense than cold air.
- Buoyancy: The lantern rises due to the buoyant force.
- Ascent Duration: It flies until the fuel burns out and the air cools.
2. What Materials Are Needed to Make Sky Lanterns That Fly?
Crafting a sky lantern requires specific materials to ensure it’s both functional and safe.
Here’s what you’ll need:
| Material | Purpose |
|---|---|
| Tissue paper | Forms the main body of the lantern; lightweight and available in various colors. |
| Bamboo or wire | Used to create a frame at the base of the lantern to hold its shape and provide a place to attach the fuel source. |
| Fire-resistant agent | Applied to the tissue paper to prevent it from catching fire too easily. |
| Fuel source | Typically a wax-based fuel cell, providing a controlled flame to heat the air inside the lantern. |
| Glue | Used to assemble the tissue paper panels and attach them to the frame. |
| Wire | Secures the fuel source to the frame. |
| Scissors/craft knife | For cutting the tissue paper and bamboo/wire to the required dimensions. |
| Ruler/measuring tape | Ensures accurate measurements for the lantern’s components. |

3. Step-by-Step Guide: How To Build Paper Lanterns That Fly?
Making sky lanterns can be a fun and rewarding project. Here’s a detailed, step-by-step guide to help you construct your own flying paper lanterns:
3.1. Design and Preparation
- Choose a Design: Decide on the shape and size of your lantern. A classic design is a simple, round or cylindrical shape.
- Create a Template: Make a paper template for the gores (panels) that will form the body of the lantern. This ensures uniformity.
3.2. Cutting the Tissue Paper
- Layer the Paper: Stack several sheets of tissue paper together to cut multiple gores at once.
- Use the Template: Place the template on the tissue paper and carefully cut out the gores. You’ll typically need 4-6 gores for one lantern.
3.3. Applying Fire Retardant (Critical for Safety)
- Ventilation: Work in a well-ventilated area.
- Spray Evenly: Lay the tissue paper gores flat and spray them evenly with a fire-resistant agent. Allow them to dry completely.
3.4. Assembling the Lantern Body
- Gluing the Gores: Overlap the edges of the tissue paper gores by about 1/2 inch. Apply a thin line of glue along the edge of one gore and attach it to the next.
- Forming the Body: Continue gluing the gores together until you have a complete, enclosed body. Let the glue dry thoroughly.

3.5. Constructing the Base Frame
- Cut the Bamboo/Wire: Cut the bamboo or wire to the appropriate length to form a circle that fits the opening of the lantern.
- Form a Hoop: Join the ends of the bamboo or wire together to create a hoop. Secure the joint with glue or wire.

3.6. Attaching the Frame to the Lantern
- Apply Glue: Apply glue around the edge of the tissue paper opening.
- Attach the Hoop: Carefully attach the bamboo or wire hoop to the glued edge of the opening. Ensure it is securely fastened.
3.7. Creating and Attaching the Fuel Cell
- Prepare the Fuel Cell: If using a pre-made fuel cell, ensure it is securely wrapped and ready for attachment. If making your own, saturate a cotton pad or similar material with wax.
- Attach to the Frame: Use wire to create a small platform or holder in the center of the bamboo frame. Attach the fuel cell securely to this platform.

3.8. Final Inspection
- Check for Tears: Inspect the entire lantern for any tears or weak spots in the tissue paper. Repair these with small pieces of tissue paper and glue.
- Ensure Stability: Make sure the frame is securely attached and the fuel cell is stable.
3.9. Flying Your Lantern
- Choose a Safe Location: Select an open area away from trees, buildings, and power lines.
- Check Weather Conditions: Only fly lanterns in calm weather with little to no wind.
- Light the Fuel Cell: Carefully light the fuel cell and hold the lantern upright, allowing it to fill with hot air.
- Release: Once the lantern is buoyant and pulling upwards, gently release it and watch it fly.
4. Safety Measures: What Should We Consider When Using Paper Lanterns?
Safety is paramount when using sky lanterns. Mishaps can lead to property damage or injuries. Here’s a detailed guide:
- Location Matters: Always fly lanterns in open areas, away from trees, buildings, power lines, and airports.
