NUREMBERG, Germany (Reuters) - A German schoolgirl has invented a "merciless bed" to ensure that sleepyheads get up in the morning.
The bed gradually raises the mattress after an alarm rings. After five minutes, the sleepyhead is rolled onto the floor.
"I constructed it myself," Iris Koser, 16, said at an exhibition of inventions this week.
