From colorful spinning machine gears in various shapes to a numbered test tube with holder, this set has everything your soon-to-be STEM-lover needs to get experimental in the bathtub.

Features:

Attach the sorter to the bathtub with the suction cups.

Fit the gears according to their shapes and colors. Each gear can be fit only with the matching shape, strengthening your childs understanding of different shapes.

Fill up water in the test tube numbered with volume marks and pour over the whole machine so the gears spin delightfully.

Show your toddler how to maneuver the large, easy-to-grasp shapes, and then spin the gears supporting their fine-motor development.

Encourage color and shape recognition by identifying them as you play together.

Put the test tube into the holder during play or for storage.
