You can even start with just one track, and add the others as your child grows. Large marbles! The large marble balls are weighted to assist with rolling down the large tracks. Each of the track sections offers a different motion effect for the marble balls. Slotted Straight Ramp – the balls bump along the straight shot from one side post to the other. Funnel Ramp! The large circular design sends balls in a vortex motion, with the chance to pass each other. The marble balls also have a chime inside, enhancing the play and learning with multi-sensory stimulation and benefitting children with varying visual abilities. As the 3 balls race, spin and zig-zag down the tracks, little ones can learn to predict the balls’ course and which will finish first. Little ones can practice fine motor dexterity and coordination by dropping the balls in and stopping them along the tracks.
