The “lightning effect” seen in carnival tricks typically relies on a scientific principle known as the Lichtenberg figure or Lichtenberg figure. This phenomenon occurs when a high-voltage electrical discharge passes through an insulating material, such as wood or acrylic, leaving behind branching patterns resembling lightning bolts.
The process involves the creation of a temporary electric field within the material, which polarizes its molecules. As the discharge propagates through the material, it causes localized breakdowns, creating branching paths along the way. These branching patterns are the characteristic Lichtenberg figures.
In the carnival trick, a high-voltage generator is used to create an electrical discharge on a piece of insulating material, such as acrylic. When a person touches the material or a conductive object placed on it, the discharge follows the path of least resistance, leaving behind the branching patterns. This effect is often used for entertainment purposes due to its visually striking appearance, resembling miniature lightning bolts frozen in the material. However, it’s crucial to handle such demonstrations with caution due to the potential hazards associated with high-voltage electricity.

2026 Public Input Report | 2026 Public Comment Report
FEMA National Risk Index: Lightning
Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.
He used a kite and a key to demonstrate that lightning was a form of electricity.
This experiment marked an important milestone in understanding the nature of electricity
and laid the foundation for the development of lightning rods and other lightning protection systems.
Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems
To paraphrase the NFPA 780 prospectus:
(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power. Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)
“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height
“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.
Related grounding and bonding requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code. This standard does not establish evacuation criteria.
The current edition is dated 2023 and, from the transcripts, you can observe concern about solar power and early emission streamer technologies tracking through the committee decision making. Education communities have significant activity in wide-open spaces; hence our attention to technical specifics.
Public input on the 2026 revision is receivable until 1 June 2023.
We always encourage our colleagues to key in their own ideas into the NFPA public input facility (CLICK HERE). We maintain NFPA 780 on our Power colloquia which collaborates with IEEE four times monthly in European and American time zones. See our CALENDAR for the next online meeting; open to everyone.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard
Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:
Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.
Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.
Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.
Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.
Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.
Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.
Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.
The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.
2024 GROUP A PROPOSED CHANGES TO THE I-CODES
When is it ever NOT storm season somewhere in the United States; with several hundred schools, colleges and universities in the path of them? Hurricanes also spawn tornadoes. This title sets the standard of care for safety, resilience and recovery when education community structures are used for shelter and recovery. The most recently published edition of the joint work results of the International Code Council and the ASCE Structural Engineering Institute SEI-7 is linked below:
2020 ICC/NSSA 500 Standard for the Design and Construction of Storm Shelters.
Given the historic tornados in the American Midwest this weekend, its relevance is plain. From the project prospectus:
The objective of this Standard is to provide technical design and performance criteria that will facilitate and promote the design, construction, and installation of safe, reliable, and economical storm shelters to protect the public. It is intended that this Standard be used by design professionals; storm shelter designers, manufacturers, and constructors; building officials; and emergency management personnel and government officials to ensure that storm shelters provide a consistently high level of protection to the sheltered public.
This project runs roughly in tandem with the ASCE Structural Engineering Institute SEI-17 which has recently updated its content management system and presented challenges to anyone who attempts to find the content where it used to be before the website overhaul. In the intervening time, we direct stakeholders to the link to actual text (above) and remind education facility managers and their architectural/engineering consultants that the ICC Code Development process is open to everyone.
The ICC receives public response to proposed changes to titles in its catalog at the link below:
2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE
You are encouraged to communicate with Kimberly Paarlberg (kpaarlberg@iccsafe.org) for detailed, up to the moment information. When the content is curated by ICC staff it is made available at the link below:
We maintain this title on the agenda of our periodic Disaster colloquia which approach this title from the point of view of education community facility managers who collaborate with structual engineers, architects and emergency management functionaries..
