It is a device to create your own mimosa.
The "Tropicana mimosa maker" is basically a spray bottle that spritzes your preferred amount of juice into your champagne.
The device has several settings: whisper, spritz and shower.
Tropicana is only selling a limited amount but says the mimosa maker would be a perfect gift for the holidays. However, if you go to the store looking to find it, you'll be disappointed. The company has only made them available through a sweepstakes on their website.
