Caffeine Check

Introduction

Worried about your caffeine intake? Now you can find out in a jiffy how much caffeine is present in your coffee mug. A new fluorescent caffeine sensor lights up like a traffic light when it detects caffeine: green for low, yellow for moderate and red for high caffeine content. All you need to do is place a coffee drop onto the detection kit and shine a green laser light onto it. The coffee would change colour depending on the amount of caffeine. The device can help heavy coffee drinkers avoid a caffeine overdose, which can cause anxiety and insomnia.
