The 130 components can be combined in a myriad of ways to create challenges for your marble races! Tunnels, curves, ramps and secret passages promise thrills around every bend. The different launchers add extra pizazz as they catapult your marbles in different directions and make sure they keep moving. Now focus on the green spiral funnel. When a marble rolls into the funnel, it rolls around and around before it falls into the bottom and continues on its way. Use a stopwatch to record the time of a marble reaching the funnel, then leaving it.

It occurs when two objects rub against each other and affects the speed of a moving object. Different materials create different amounts of friction, or resistance. If a marble rolls across a rug, it would move more slowly than across a wood floor.This construction toy lets you construct a variety of builds with color-coded building pieces and easy-to-follow instructions and makes a great gift for kids 4+ years

Children are sometimes referred to as intuitive physicists, biologists and even psychologists. This means that children may naturally understand something about how the world around them works. Infants are beginning to understand about physical objects and their effects upon one another. They also learn a great deal about the world around them by repeating actions that have an effect. For instance, infants demonstrate their understanding of ‘object permanence’ when they pull away a blanket to reveal a toy that has previously been hidden from view. Young children continue to build knowledge of their world by acting on the environment around them.

CAUTION: Not suitable for children under 36 months. Choking hazard due to small parts that can be swallowed
