Henry and Jack Grover, students at Riverside STEM Academy, developed a hydrogel treatment using sodium polyacrylate to prevent charcoal reignition. Their innovation successfully delayed fire flare-ups significantly longer than water alone.
Why it matters
The brothers sought to address the challenge of preventing fire reignition, aiming to provide a more environmentally friendly alternative for firefighters. Their research provides a new potential tool for managing burned areas.
The twins tested nine distinct hydrogel materials before identifying sodium polyacrylate as the optimal choice. Their custom 3D-printed sprayer, which attaches to a garden hose, can project the treatment up to 18.3 metres.
The players
Henry and Jack Grover
These middle school students at Riverside STEM Academy were named finalists in a national science competition for their work on fire safety.
Thermo Fisher Scientific Junior Innovators Challenge
This national competition recognizes young scientists for their original research and innovation in STEM fields.
The details
The process involved testing hydrogels for hydration, drying, and adhesion before applying them to hot charcoal. The resulting treatment allows for safer, more efficient cooling of materials prone to reignition.
Timeline
October 23 to 28, 2026: Finals Week for the Junior Innovators Challenge in Washington, DC.
The Big Picture
This project participates in the broader trajectory of the Thermo Fisher Scientific Junior Innovators Challenge, which highlights student-led innovation. The research demonstrates a shift toward practical, scalable applications for chemical engineering in public safety.
This development could eventually lead to more efficient, eco-friendly fire suppression tools for residential and municipal use. Future applications may include safer ways to manage brush fires or prevent accidental re-ignitions in outdoor settings.
The takeaway
The study highlights how common materials like sodium polyacrylate can be adapted for high-stakes fire safety through scientific experimentation. It demonstrates that student-led research often provides practical, low-cost solutions to complex environmental hazards.
What happens next
The twins will compete for the $25,000 Thermo Fisher Scientific ASCEND Award during Finals Week in Washington, DC, from October 23 to 28, 2026.
