Fizz! (Photo by Rieko Suzuki)

Making fizzy candies with kids can be an educational activity. The bubbling sensations and the coolness of these treats are given by the carbon dioxide that results from mixing baking soda (sodium bicarbonate) and citric- acid water in your mouth. Keep the candies in a sealed plastic bag or lidded jar to avoid humidity. Food coloring is optional—but it helps make these a treat for the eyes as well!

Cooking time: 4 h (active 15 min)

Servings: 15 medium-sized candies

Ingredients

• 50g powdered sugar
• 10g corn starch
• 1/3 tsp baking soda
• 1/4 tsp citric acid (available at drug stores)
• 1/2 tsp lemon juice
• 1/2 tsp water
• Optional: 1 drop food coloring
• 2 small cans, or 700cc beer of your preference

Directions

1. In a mixing bowl, combine powdered sugar, cornstarch, baking soda, and citric acid. Mix well.
2. Add lemon juice to the batch, and mix well.
3. Add water to the mixture; if you’re adding food coloring, mix it in with the water, in advance. Mix well.
4. With small spoon, scoop up sufficient amounts from the mixture and flatten with fingers, then lay out on a paper towel.
5. Leave for 3-4 hours in dry place so candies harden.
