Have you ever tried the baking soda and also vinegar balloon experiment? This classic self-inflating balloon scientific research experiment is really one of my favorites. It is so straightforward to do and also it really is amazing to watch.
You are watching: Self inflating balloons
The reaction in between the baking soda and also vinegar cause the balloon come inflate every on its own! It is a show-stopper experiment for kids.
(See an ext of my STEM projects for kids.)
How to execute the Baking Soda and Vinegar Balloon Experiment:
Supplies girlfriend Will need for the Experiment:
Plastic water bottle, emptied
1 Large Balloon
TIP: Before beginning the experiment, friend will want to stretch the end the balloon to do it more loosened and simpler to inflate.
Step 1- to water 1-2 spoonfuls of baking soda into the opened of the balloon, making use of a funnel. You’ll should shake that a little bit to get it down right into the basic of the balloon.
Step 2- usage the funnel again and also pour part vinegar into the plastic bottle till it is around an customs or two deep. Exact quantities do not matter.
Step 3- closely stretch the opened of the balloon approximately the mouth of the bottle leaving that hanging down till you are all set for the reaction.
TIP: Don’t let any kind of of the soda dump right into the party while it is registered it.
Step 4- as soon as you are ready to view the chemistry reaction happen, lift up the balloon enabling the baking soda to autumn down into the bottle.
This is once the funny starts! Baking soda and vinegar produce an awesome chemical reaction. The gas from combining the 2 will reason the balloon come inflate. It’s impressive. The much more gas there is created, the larger the balloon will get.
Your kids, if they space anything like mine, will certainly beg to carry out it again, climate 10 much more times! This is yes, really a perfect science task for kids to shot on their own.
If you perform repeat it, girlfriend will require fresh vinegar in the bottle. When a reaction happens, it is not fairly so solid the 2nd time through. The balloon walk not typically inflate again uneven the vinegar is fresh.My children were amazed and wanted to do it again and also again and again. Share up ~ above baking soda and vinegar if you room planning this one! Luckily they room both quite inexpensive.
(It’s a good thing they are both therefore cheap!)
The scientific research Behind It: Why walk Baking Soda React v Vinegar?
When the vinegar and baking soda combine there is a reaction in between an acid and a base. Vinegar is the acid and also baking soda is the base. This reaction between the two reasons a gas referred to as carbon dioxide come bubble and foam. This gas having nowhere rather to go, expands the balloon making the self-inflating balloon happen.

We love the carbon dioxide reactions that these 2 substances create.
