A student who was unable to get up in time for lectures has invented an alarm clock that can shock owners awake.
Sankalp Sinha, 19, came up with the idea after getting into the habit of hitting the snooze button on his alarm clock and then going back to sleep.
The teenager tried to think of something which would force him out of bed and so invented one that administers a small electric shock via the snooze button.
When the user presses the aluminium-coated snooze button on the top of the clock, harmless micro-volts of electric current are emitted to jolt them into life.
The power is a fraction of a volt compared to the 50,000 volts administered by a standard police Taser gun and under one volt.
Once it becomes available Sankalp expects it to sell for around £60 on the high street.
