@Usmansh more from that month

This was implemented way before there were no alarms. They knew how to calculate the time, they put nails in the candle according to it. When the candle melted to that point, the nail would be dropped on the steel plate which would make the person wake up. Thankfully, we have alarms now, cos the sound of nails on the steel plates is not enough to wake me up. 😂😂
