|Meyall Newton’s Cradle Balance Balls, Art in Motion Toys for Kids Adults, Science Physic Psychology Educational Kits (Medium Size)
Lowest new price: $15.59
History of Newton's Cradle:
Newton's cradle (also known as Newton's balls or Executive Ball Clicker), named after English 17th century scientist Isaac Newton, is a device that demonstrates conservation of momentum and energy using a series of swinging spheres.
When one sphere at the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last sphere upward.
Newton's Laws of Motion: "For every action there is an equal and opposite re-action."
Fine argument of Newton's law of motion and the starting point of physics. Inspired us to better understand the concept of conservation of momentum. Demonstrates Conservation of mechanical energy.
Newton Cradle will never be outdated. It's great for physical teachers, students, office workers, kids, men and women at all ages.
Size: 5.5x5.1x4.4 in
Material: Solid wood+ Fishing line+ Stainless steel balls & structure
Occasions: Science Education supplies, Psychotherapy, Stress release, Leisure and entertainment, Birthday present, Holiday gifts, Business gifts

|Rattleback - Plastic Assorted Colors - Pack of 10 with Teacher's Guide
Lowest new price: $12.99
Brand: American Scientific
The Rattleback is a long and thin half-elliptical shape formed in plastic so that it has a slightly offset center of gravity. This offset gravity causes the Rattle back to spin in directional rotation of choice, usually counterclockwise. If you attempt to spin the Rattleback in the clockwise direction, strong preference will cause the Rattleback to "rattle" back and forth after few rotations, stopping and then reversing the rotation back to the preferred counterclockwise direction. The directional preference is so strong that if the Rattleback is at a standstill and you push down on one end it will begin turning. Color may vary. Comes with Teacher's Guide.
- Assorted colors
- Includes Teacher's Guide
- Each one measures approximately 98mm or just under 4 inches.
- Pack of 10
