Features
- Color: As Shown
- Material: Plastic, metal
- Size: About 23. 00X4. 50X3. 00cm/ 9. 04X1. 77X1. 18in
- Let the metal ball pass through the ring several times to show that the metal ball can pass through the ring at normal temperature.
- Heat the metal ball for 3- 5 minutes, and then pass the metal ball through the ring.
- At this time, the metal ball expands due to heat, so it cannot pass through the ring.
- Design to prove the effect of thermal expansion and contraction.
- Great physical teaching aids for teacher.
- Color: As Shown.
- Size: 23X4. 5X3CM.
