Breathe. Or you can put baking soda in vinegar. That will release CO2.

Place any carbonate (chalk, seashells, limestone, baking soda, etc.) into an acid solution. The bubbles you see rising from the solid are carbon dioxide. The stronger the acid the faster the CO2 will be produced. Also, the finer the solid matter is divided, the faster the reaction will take place. Because baking soda is very finely divided, it will produce CO2 very rapidly, but not for very long, even in a weak acid like vinegar.
You can collect the CO2 in a couple of ways. Put a 1-hole stopper with a short tube snugly into the mouth of the reaction container. Then you can run a rubber tube from the reaction container into a pan of water, in which is an inverted, water-filled jar. Place the end of the tube under the opening of the inverted jar and allow the CO2 to bubble up into the jar, replacing the water. Once the jar is full of CO2, stopper it while still inverted underwater. Or, attach the mouth of an ordinary party balloon to the short tube protruding from the stopper, and allow the balloon to inflate with CO2.

CO2 is a byproduct of human repiration. You exhale CO2

Put yeast in water with a lot of sugar. The yeast will produce a lot of CO2.

Yup..Just breath out....You exhale CO2

put a plant in a room, with no light. it will perform cellular respiration and not photosynthesis, releasing co2
