This device helps not to be distracted by shooting a stream of coffee at the owner

Engineering thought sometimes bypasses common sense, but hits the target right away. One inventor has assembled a device that sprays coffee directly at the user every time he or she gets distracted from work and opens unnecessary tabs.

The mechanism is ruthless and acts instantly - you just have to try to turn on a video with a cat, and the face gets an invigorating response.

It all works next to a laptop, which makes the idea both useful and risky, especially if you value your keyboard. However, it is still not the worst way to train your attention and wean yourself off digital temptations. Get distracted - get an espresso in the forehead.
