When i was in class 4 ,I had a small 5v bulb(glass bulb small one),when I used to connect it to the 1.5v battery it emmited very less light so I instead plugged it into wall and turned on the switch and it blew up instantly,the power in house went out and my big sister went to check everything out,I instantly grabbed a cloth and wiped out the black stains from switch board , but a new problem arises ,that was it was looking more clean than other boards in my house, but they never found out it was mentioned who did it.
