If you drop one of these magic tablets into a glass of water it will instantly begin to dissolve, creating a cascade of bubbles that will infuse the water with a delicious new flavor. But don’t limit yourself to water. These Effervescent Drink Tablets work just as well in milk, juice or soda. Great for making bizarre beverages or slipping into a friend's drink when they’re not looking. Each 2-1/4" (5.7 cm) round tin contains about fifteen tablets.
