It's never too early to encourage a love of science -- and the bath is the perfect place for toddlers to learn! Turn your tub into a simple science lab with our ColorMix STEM Bath Toy. This fun learning toy teaches cause & and effect through color mixing experiments that are safe, nontoxic, and non-staining. First, suction the toy to your tub wall and drop one colored bath tablet into each slot. Add water to activate and mix, then twist the knob for a colorful, sprinkling cascade! Nothing compares to a child's sense of wonder when discovering something new. Just add water and color your mini chemist's world with mess-free, stress-free learning fun. What a brilliant addition to the bath routine!
