  • 音樂讓我不想看...

  • 摇动是上锁,木的圆洞里还有木头。当你旋转时,锁的那块木就被甩­到旁边了。

  • 若果他的題目寫「探究圓週運動」我會讚好

    但他說這是魔術我覺得好流LO

    整左2個洞係度傻既都知道咩料LA

  • 1號木頭上方有個洞 2號木頭是在凹槽裡面 2號木頭的洞裡有根小木棒 搖一搖之後 小木棒卡在1號木頭的洞中間 = 卡住 轉一轉 小木棒 被甩到2號木頭的洞的最裡面 = 開啟 我推測的啦 =ˇ=.... 跟正常的鎖差不多 不用鑰匙就對了...

  • 這音樂。。

  • 是我听错,还是那背景音乐……汗颜

  • three small

  • 哪裡買得到???

  • 是不是在轉動時將十字鎖裹面的木條引力扔出.

  • 中間有個卡損  會動..
