The Tangle Jr. Glow in the Dark twists ordinary fidget play into a glowing hands-on experiment. Bend, loop, and connect the flexible segments, then watch them light up after absorbing energy from nearby light sources. Inspired by phosphorescence and glow chemistry, this endlessly movable fidget toy keeps curious hands busy day or night. Perfect for sensory play, focus, and anyone who thinks science is even cooler in the dark.
