The Twist Alarm Clock
Japan and its alarm clocks. This so-called Twist Alarm Clock , makes you solve simple math problems.
The way it works is that when the alarm starts ringing in the morning, the clock uses its two displays and two rotatable parts to create a math problem, for example 8+2=?. It won’t stop ringing until you give it the right answer. 5-4=2, as seen in the picture above, won’t work. Maker D-Forme says the main idea behind their clock is to force buyers to activate their brains in the morning.
You can buy one for only $30 from Japan Trend Shop if you live in Japan 😀 . If you don’t you can contact them and ask them if they ship to your country.
