Be mesmerized by this calming pendulum as it traces lovely Lissajous patterns in fine sand. Use it to study harmonic motion as energy is transferred from the pendulum swinging in one plane to another at right angles. Secured in its plastic stand, the all metal pendulum converts kinetic energy into potential energy. Standing at 38 cm, this compact rhythmic pendulum is an elegant desk ornament that demonstrates real science and offers great value for money.

Age: 10+ with adult supervision.

What You Get

All metal sand pendulum standing 38cm high. Plastic base (17cm in diameter). Sand.

How does it work

Give the pendulum arm a push and watch as gravity and the earth's rotation take over creating geometric patterns in the sand. The fine sand provides minimal friction allowing the pendulum to swing for up to 5 minute periods as it gently "writes".
