A selection of the coolest, wildest and most fascinating materials. Includes hydrophobic sand, glow in the dark putty, polymer snow, alum, magnetic putty and sand slime.
Our glow in the dark putty may be pale in daylight but watch it become vibrantly alive as you dim the lights! Expose it to a bright light during the day or in front of a direct light to unleash its “glow in the dark” potential.Â
