It’s fizzy because the gas carbon dioxide is pumped into it. Before you open the bottle, most of the gas is trapped invisibly in the drink. But when you unscrew the top, the gas is released and forms thousands of bubbles.
Making a fizz
Why not try your own fizzy experiment? Add baking powder to water and watch what happens. When it mixes with water, it makes bubbles of carbon dioxide, too.
Some sodas are naturally fizzy. This means they make their own natural gas – like root beer.
The very first fizzy drink was made in 1772, by a British scientist called Joseph Priestly. He hoped he’d mad a medicine. He hadn’t but the drink caught on!.
When you breath out, carbon dioxide is one of the gases in your breath.

What you need:
Squeeze the lemon juice into a small plate with a few drops of water and mix with a spoon.
Dip the toothpick into the lemon juice mix and write a message on the white sheet of paper.
When it dries the writing will be invisable.
Heat the paper by holding it over a lamp with the writing side down.
The invisible ink writing will slowly turn brown and appear on the page!
The perfect craft for a rainy day! Be inspired by those rain clouds and get making your own. They’ll be a nice addition to the other arts and crafts on the display wall.
What you need:
Cardboard (recycle a cereal box)
Step 1. Cut cardboard into a cloud shape.
Step 2. Cut cellophane into strips.
Step 3. Glue the bottom of the cardboard and place the strips of cellophane on it.
Step 4. Overlap the cellophane strips with more so it’s a downpour rather than a shower!
Step 5. On the same side, glue again and stick the cotton wool balls all over the cloud, filling it in.
