The downside of throwing a party is that guests can't always be relied upon to sparkle, so it's as well to have a flashy effect or two up your sleeve to avoid those conversational blackspots. If the chit-chat should falter, simply press the button on the base of your glass & it will come to life & create a real buzz of delight amongst your guests. With seven rainbow colours to choose from, the style conscious will be relieved to learn that glass & contents are in no danger of clashing, while a multicoloured medley of illuminations produces a near pyrotechnic finale. So if you're into the low light party look, the room will be a awash with the glorious glow of these stunners. The glasses also come into their own in the event of power cuts & are a cunning way to alert those wandering round with the bottles that you're ready for another.
