Levanger Fire Officials Issue Urgent Warnings Over Plumbo Explosives
Emergency responders in Levanger, Trøndelag, are confronting a dangerous youth trend centered on homemade chemical explosives crafted from heavy-duty drain cleaner and water. Fire Chief Arne Reitan Sæther issued a stark warning regarding individuals mixing strong liquid drain cleaner with water inside plastic soda bottles. The mixture triggers a volatile reaction, building extreme pressure until the container bursts with the sound of a high-powered rifle shot, as Dagbladet reported. Fire crews have increasingly picked up remnants of homemade Plumbo bombs in central Levanger, noting that local newspaper Innherred and Trønder-Avisa first covered the issue.
Eight Blasts Disrupt Stadionparken on a Single Saturday
The scale of the activity became starkly apparent on a single Saturday evening. Authorities discovered eight exploded plastic bottles scattered across Stadionparken in Levanger. Local newspaper Trønder-Avisa first reported on the cluster of blasts. Fire crews have been repeatedly dispatched to clear hazardous debris from town center parks and walkways.
Fire officials emphasize that these devices are far from harmless pranks. They carry significant risks of severe injuries from flying plastic splinters, high-pressure shockwaves, and caustic chemical burns.
Corrosive Residue Creates Hidden Hazards for Children and Pets
Beyond the immediate danger of a premature detonation in a teenager’s hand, the explosions leave behind pools of corrosive powder and liquid residue on the ground.
Fire Chief Sæther cautioned that this leftover chemical material poses a severe hazard to small children playing in neighborhood parks and to loose domestic animals that might come into contact with the toxic substances. Because the chemical reaction inside sealed bottles remains unpredictable, responders never know how long a volatile device will take to trigger, creating hidden landmines for unsuspecting residents who attempt to clean up public areas. Officials noted that shaking the bottles builds up pressure causing explosions, and pointed out that unexploded devices might be found by neighborhood residents who do not know what they are.
Appeals Directed at Retailers and Parents to Curb Sales
Local emergency leadership is urging parents to monitor their children’s activities closely. Officials are also asking local retail stores to exercise heightened vigilance when young customers attempt to purchase heavy-duty drain cleaning products like Plumbo.

Sæther noted that twelve-year-olds buying industrial cleaning agents have no legitimate need for clearing household pipes. Officials decided to publicize the dangerous phenomenon in the hope that teenagers will choose safer recreational activities once they understand the life-altering consequences of chemical shrapnel and severe skin burns. According to Sæther, authorities initially hesitated to publicize the trend in the media and on social media out of concern that it might give people ideas, but ultimately shared warnings online stating that the activity is not an innocent joke.
