Einstein Science Stuff Lab Tube - Glow in the Dark Putty From Purple Cow Who doesn’t like putty? That’s right – no one! This one is special – it glows in the Dark. Our glow in the dark putty may be pale in daylight but watch it become vibrantly alive as you dim the lights! Colorful Glow in the dark putty glows with lighting effects in dim light. Expose it to a bright light during the day or in front of a direct light to unleash its “glow in the dark” potential. The chemicals inside our putty are called phosphors, and they emit light after absorbing energy from another source like the Sun or a lamp. Age 13 Plus
