【阿里巴巴大叔的话】还记得2月刊上和大叔一起做的玩具吗?导线像个跳舞的姑娘,一直转啊转。今天,大叔把难度加大,来考考大家:要是没有电池,大家还能不能做出转不停的玩具?【材料】1只纸袋,1条5厘米宽的纸条,1根金属毛线针(或者两头稍尖的直铁丝),1个橡胶塞(或者1块大橡皮),1个按扣,1段双面胶,1把美工刀,1杯热水。另外需要借助数学器材——圆规、量角器和直尺。(刀子和热水危险系数大,大家可要当心。父母有空的话,一起做亲子游戏吧。)
【Uncle Alba Baba’s words】 Do you still remember the toys that were made with the uncle in the February issue? The wire is like a dancing girl and has been turning around. Today, Uncle to increase the difficulty to test everyone: If there is no battery, we can not make non-stop toys? [Material] 1 paper bag, a 5 cm wide strip, a metal wool needle (Or slightly pointed straight wire), a rubber stopper (or a large rubber), a button, a double-sided tape, a knife, a cup of hot water.
