Some of very Easy Science Experiment Projects For School Going Kids

Science Experiment To Explain Hypothesis of Balloon, Vinegar and Baking Soda

The hypothesis behind this experiment is very simple which involves the properties of gas. The gas evolved in this experiment is used in blowing up the balloon. This science experiment of balloon, vinegar and baking soda also explains that the carbon-di-oxide is evolved when the mixture comes into contact.

Follow the steps for experiment of Balloon, Vinegar and Baking Soda :

1) Take a clean plastic or glass bottle and see to that you are able to hold the balloon cap on to it firmly. Place the bottle removing its lid onto the bench and fill three spoons full of vinegar (acetic acid) in it.

2) Open up the mouth of the balloon and put three to four spoon of baking soda (sodium bicarbonate) and carefully place the balloon over the bottle without the mixture falling down. Check whether the balloon is neat and no tearing or hole is found on it.

3) Once the baking soda in the balloon comes into the contact with the vinegar in the bottle, a chemical reaction occurs. As the product of it, the carbon-di-oxide is produced.

4) This produced will not find anywhere to move out and hence it moves into the balloon and makes it blow up.

Watch out:

• If you cannot find immediate reaction then shake the bottle very well and see to that the mixture is mixed up evenly.

• There is no chance for the balloon to burst out but for the safe side try to maintain the kids little far away and watch the experiment.

• To obtain more gas and bigger size of balloon add more vinegar and baking soda.

• Once the balloon is used in the experiment don’t try to blow it up through your mouth (even after washing up) as the carbon-di-oxide (CO2) is highly dangerous to health.
