Riverside siblings Henry and Jack Grover have been named finalists in the 2026 Thermo Fisher Scientific Junior Innovators Challenge. Their project features a biodegradable hydrogel designed to prevent wildfire reignition from smoldering materials.
Why it matters
The development addresses the challenge of wildfires persisting due to hot, smoldering debris after initial containment. The twins aim to provide an environmentally friendly alternative to current chemical retardants.
The hydrogel, composed of sodium polyacrylate, kept treated charcoal from reigniting for 27 minutes. The inventors also developed a specialized sprayer capable of applying the material from a distance of 18.3 metres.
The players
Henry and Jack Grover
These Riverside-based twin brothers are the student inventors behind the hydrogel project.
Thermo Fisher Scientific
This company sponsors the Junior Innovators Challenge, a national competition for young scientists.
The details
The inventors assessed nine different hydrogels by measuring weight changes through soaking and oven-drying cycles. They also tested the material's adhesion properties by applying it to leaves and calculating how much of the gel was lost.
Timeline
The Palisades fire occurred in 2025.
The twins were named competition finalists in 2026.
Finalists attend the competition in Washington, D.C., from October 23 to 28, 2026.
The Big Picture
This project aligns with the goals of the Thermo Fisher Scientific Junior Innovators Challenge by promoting student-led innovation in environmental safety. The research marks a shift toward accessible, biodegradable chemical solutions for wildfire management.
The successful application of biodegradable hydrogels could eventually lead to safer, more effective residential wildfire protection tools. Future developments may offer homeowners a viable way to coat property surfaces to prevent ignition from embers.
The takeaway
Innovative solutions often emerge from applying existing materials like sodium polyacrylate to new environmental challenges. Protecting homes from smoldering debris requires continuous, creative experimentation with material adhesion and durability.
What happens next
The 30 finalists, including the Grover twins, will attend the competition's Finals Week in Washington, D.C., from October 23 to 28, 2026, where they will compete for $100,000 in total awards.
