While at play with these beautiful new Kodo Finds, your children will be using not only their bodies but their minds, too!

Experiment with drag, force and buoyancy by adding more weight to the suspended pocket. Each Silk Parachute comes with a small rubber ball but we suggest adding large washers, gems or even pebbles. Used outdoors or in, it will not only delight your children but lead to wonderful investigations. Archimedes principles in the preschool classroom - you betcha!
