Footlume glowing rug
You may be in a dilemma when you want to pee at midnight: on the one hand, your drowsiness might be weakened because of the strong light; on the other hand, if you walking in the dark, your toes may be stubbed or drink some pee.
Fortunately, thanks to two students at London’s South Bank University, this glowing rug with a pressure sensor will light up and guides you when you stand or walk on it.
