12 Genius Things That Actually Exist And 12 Insane Things That Should Not Exist

10. Indicator lights for bikes.

With more and more people opting to get around via bike, these things should be built-in. Yes, there are hand gestures that bikers use to indicate changes in speed, upcoming turns, and lane changes, but most non-bikers don’t know what the gestures mean. BlinkerGrips definitely make sharing the road a lot safer!

11. Tiny trackers for all your important stuff.

Tile is a Bluetooth tracking system that syncs with a smartphone app. If you misplace one of your tagged items and it’s within 100 feet, you can make it ring from your phone. If it’s outside that range, just hit “last place seen” and it will show you on a map.

12. Nasal screens.

At first glance, I thought “This is a stupid idea.” But then I read about the product and changed my tune. These nasal screens stick to your nostril and filter the air you breathe, reducing allergens, germs, and even disease-causing pathogens. They’re also discreet. These would be great for travelling to places with poor air quality.
