What you want:
- Plastic sandwich bag
- Baking soda
- Vinegar
- Teaspoon
- Measuring cup (1/4 cup)
- Small sq. of bathroom paper or paper towel
- Permanent markers
What you do:
Step 1: Draw a snowman’s face in your plastic bag.
Step 2: Put two teaspoons of baking soda on a small sq. of bathroom paper or paper towel, and wrap it up.
Step 3: Put the baking soda bundle within the plastic bag.
Step 4: Pour 1/4 cup of vinegar into the bag, and seal it rapidly.
Step 5: Stand again and watch your snowman develop.
Safety be aware: Stand a protected distance away out of your bag in case it pops. If it does, accumulate any small items of plastic to forestall choking hazards for younger kids or pets.
Now do that: Use a much bigger bag and check out completely different mixtures of vinegar and baking soda.
What’s happening: Your snowman expands due to a easy acid-based chemical response. Baking soda, or sodium bicarbonate, is a base that reacts with vinegar, which is an acid often called acetic acid. The two substances mix to provide carbon dioxide fuel. Carbon dioxide is the fuel that we breathe out.
