6. Magic mirror
5. Small fans
While the whole world is suffering in hot weather, using air conditioners, and drinking cold beverages, Japan has come up to a great idea: a small portable fan.
For men these are headphone-like fans, pocket devices for shirts and shoes, and a great cooling fridge.
For women these fans are attached to a selfie ring light and a cooling carpet for a laptop that you can cover your pillow with.
