The Right Cup is a scented drinking cup to "flavor" your water without adding calories:
The Right Cup is a glass with a scented inner lining that convinces you you’re drinking a sugary fruit juice instead of good old plain H2O. Intended to curb cravings for flavored drinks, the product will help you reach the eight glasses a day of water needed with a rush of flavor.
[...] The Right Cup’s material has a proprietary Encapsulated Aroma Release technology that lines the inside of each cup. When you put water in and hold it close to your face to drink, the aroma gets sniffed while the bland water is being chugged down. The smell will “fool” you into thinking you’re drinking a flavored drink.
The cups will sell for around $35, and the company is planning a crowdfunding campaign later this month. You can read more at Cup Uses Aromas to Fool You Into Drinking Plain Water at psfk, or sign up at The Right Cup's website to be notified when they are available.
