Feature

●Physical experiment material-- use the small ball through the ring at room temperature.
●Expansion and contraction experiment-- demonstrate solid or metal thermal expansion and cold contraction phenomenon.
●Tools-- let the metal ball pass through the ring several times to show that the metal ball can pass through the ring at normal temperature.
●Supply-- made of materials for durability.
●Physics experiment material-- the metal ball is then placed on an lamp and heated for 3- 5 minutes, it can not pass through the ring.
