Is the Correct Way to Hold Sparklers "Diagonal" Instead of "Vertical"? — A Complete Guide on How to Hold Them, Regional Differences, and Tips for Longevity from a Manufacturer with Nearly 100 Years of History

1. Conclusion: Vertical is "No", 45 Degrees is "Correct"

• Manufacturer's Experiment Results
  A representative from the long-established manufacturer, Onda Fireworks Department, explains, "Straight vertical is 'no'. 45 degrees allows for longer playtime." In experiments, the fireball fell quickly when vertical, while it lasted longer on average when angled (e.g., vertical 21 seconds / angled 24 seconds, with an average of 26 seconds vertical / 30 seconds angled over six trials). The reasoning is that angling increases the 'contact surface' of the fireball, making it less likely to fall, according to combustion physics. Additionally, **"twisting the tip slightly"** helps the gunpowder to consolidate, allowing for a more stable and prolonged enjoyment.Mezamashi Media
  
  

• Why Did "Vertical" Spread?
  Sparklers are weak against wind, and the image of "vertical and still" has taken root to ensure stable and motionless hands. However, from the perspective of maintaining the fireball longer, angled is more logical, as shown by the latest manufacturer verification.Mezamashi Media
  
  

2. Different "Sparklers" in East and West—Two Types and Ways to Hold

In Japan, there are mainly two types of sparklers.

• Nagate Botan: A type wrapped in paper with gunpowder. Popular in Kanto. The basic enjoyment is to point it downward at an angle.

• Subote Botan: A type closer to the original, with gunpowder on the tip of straw. Popular in Kansai, and the tradition of pointing it upward at an angle remains.
  Recently, imported products have increased, and due to the "fragility" of the fireballs falling easily, the way of holding them has become more important.Weather News
  
  

Good to Remember: You will often see Nagate Botan. In any case, avoid the wind, angle it, and focus on the "position where the fireball stays" to make it beautiful and long-lasting.Weather NewsWikipedia

3. The "Aesthetics" of Sparklers—Don't Miss the Four Expressions

Sparklers display four stages from ignition to extinction.

1. Bud: The fireball is born and quietly swells.

2. Peony: Crackling and grainy sparks.

3. Pine Needles: The momentum increases and thin fire trails burst in all directions.

4. Chrysanthemum Scatter: The light thins, and the sound quietly ends—this lingering evokes "mono no aware."Weather News
   
   

For English-speaking audiences, explaining it as Senko hanabi facilitates understanding. After ignition, molten "fire drops (slag)" form, from which fine sparks burst—this unique mechanism creates delicate expressions.Wikipedia

4. Practical Tips for "Longevity": Three Points Useful on Site

1. The angle should be "45 degrees"
   The contact surface of the fireball increases and stabilizes.Vertical is prone to falling and disadvantageous.Mezamashi Media

2. "Twist the tip slightly"
   The gunpowder consolidates, increasing the paper's strength, and extending the duration. Don't overdo it.Mezamashi Media

3. Avoid wind, keep hands steady
   Even a light breeze can disrupt the fireball.Stay in the shelter of a windbreak, and keep your hand steady. In English guides, saying "steady hands, no wind" is effective.Wikipedia
   
   

Trivia: Storing with "breathing" humidity can enhance the beauty of the sparks. It is said that repeating drying and moistening until the next year improves the integration of the gunpowder.Weather News

5. Setup for Beginners

1. Choosing a Location: Check local regulations. Beaches and parks may be prohibited areas. Balconies in apartment complexes are often generally not allowed.

2. Safety Preparations: Bucket of water, metal tray, heat-resistant gloves (when children are present), and a fire extinguisher bottle.

3. Ignition: Transfer the fire with the tip (gunpowder side) down. Choose a windless direction, and angle it at 45 degrees.Wikipedia

4. Appreciation: Quietly enjoy the four stages of expression. Value the afterglow over "competition."

5. Cleanup: Ensure complete extinguishing before sorting. Drain moisture from the ashes before disposal.
   
   

6. Manners and Etiquette

• Savor the Quiet: Sparklers are the opposite of loud fireworks. Be mindful of the time in residential areas and at night.

• Take Your Trash Home: Gunpowder paper and straw can scatter easily. Cleaning up is part of the "etiquette".

• Accompanying Children: Adults should assist with ignition and angle. Sparks can create holes in clothing.

• Photography: Be careful not to obstruct others' viewing with tripods or smartphone lights.Ensure they do not interfere with others' enjoyment.
  
  

7. Common Misunderstandings Q&A

Q1: Isn't vertical "more stable and longer-lasting"?
A: No. The way the fireball "sits" is important, and 45 degrees increases the contact surface, making it less likely to fall. Experiments also show that angled lasts longer on average.Mezamashi Media

Q2: Do imported products fall quickly?
Many tend towards the "fragility" of fireballs falling easily. However, with techniques for holding and wind avoidance, they can be enjoyed beautifully.Weather News

Q3: What is the correct ignition direction?
With the gunpowder side down. Avoid wind and keep your hand steady for best results.Wikipedia

8. Cultural Background: Why Are People Drawn to "Quiet Fireworks"?

Sparklers are a product that appreciates the beauty of transience over showiness. In English guides, adding the concept of **mono no aware** helps convey the
