V is for Vinegar Volcano !!

This is another fun experiment we tried during the mid year if I didn't remember wrongly. We bought the kit from Toy R Us or you can find them at Kiddy Palace.

The usage of using baking soda and vinegar, creates an awesome chemical reaction! Watch as it rapidly fizzes over the Volcano model and make sure you've got some towels ready to clean up or put the model into a plastic container big enough to accomodate the size of the volcano if you dread clearing the mess.

First, I assembled the vocalno model and Xav painted it.

After that, just prepare the following below :
•Baking Soda (make sure it's not baking powder)
•A container to hold everything and avoid a big mess!
•Paper towels or a cloth
•Red paint
•a pump of handwash for a foamy effect if you want

1.Place some of the baking soda into your container / vocalno model.
2.Pour in some of the vinegar
3.Watch as the reaction takes place!

What's happening?
The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.

Try it out this weekend ! Have fun !
