Poland recently unveiled a glow-in-the-dark bike lane near Lidzbark Warminski. This thing is done to make cycling safe and accessible in the dark hours of the day.
This mesmerising lane is built by a company called TPA Instytut Badań Technicznych Sp. z o.o, it can glow blue up to ten hours after getting charged by the sunlight, yes you guessed it right they are solar-powered.
These are created using a synthetic material called phosphor and is directly charged by the sunlight in the day time and then glows up to ten hours in the dark.
The path is currently in the test phase but it will soon prove to be a success!
