“Toothpick crossbow” and then there are hluav taws xob cov khoom ua si into the campus instantaneous voltage over 600 volts
Not long ago, there was a dangerous toy called a toothpick crossbow into the campus quietly. And recently, among the primary and secondary school students, they began to gradually pop up a kind of electric toys.
