Step 1 – Start with an empty two-liter bottle and secure a balloon around the mouth of the bottle. Helpful Tip: 8-inch balloons work best for this experiment. When we tried this with a 10-inch balloon, it didn’t inflate entirely. Step 2 – Prepare two pans of water. Fill one pan with ice and cold water.
Pour 4 tablespoons of vinegar into the bottle. 2. Use the funnel to add 1 tablespoon of bicarbonate of soda into the balloon. 3. Pull the neck of the balloon over the neck of the bottle without releasing any bicarbonate of soda. 4. Lift the balloon so that the bicarbonate of soda falls from the balloon into the bottle and mixes with the vinegar.

Pour the vinegar into the bottle. Carefully fit the balloon over the bottle opening (be careful not to drop the baking soda into the vinegar yet). Once the balloon is fitted snugly on the nozzle, hold up the balloon and allow the baking soda to fall into the vinegar. Observe the chemical reaction and effect on the balloon.
31 de may. de 2021 · The weight of one cubic foot of air is 0.0807 pounds at 14.7 psi. If we compress the compressed air to 1000 psi, then the air weight per cubic foot is beyond 5 pounds. In this way, compressed air weight is calculated based on the pressure it is experiencing. Check out other air pressure experiments: Egg in a Bottle Experiment.
