Seince Projects: Chemical Reactions.

From now on in my school work the Sience Projects I do I will write them in my blog...

This project is called:

Chemical Reactions.
(in this chemical change, vinegar and baking powder react and give of a gas)

1) Firsd I poured vineger in a plastic bottle about half inch deep...
2) Then I poured 2 tea spoons of baking powder/soda in to the neck of a baloon...
3) Then I streched the neck of the baloon over the neck of the bottle, being careful not to let baking powder out of the baloon...
4) Then I lifted up the baloon and let the baking powder out and I shaked the bottle...

The baloon blew up half way itself!!!

The lesson is (i'm reading the book): "When the two substances react together, they form new chemicals or products. One of the products here is carbon dioxide, as bubbles of the gas, which inflate the baloon.


My lesson is that both the vinegar and the baking bowdere that makes chemicals and makes air to blow up the baloon...

If you want you can do this project, your suppose to use a funnel for the vinegar in the bottle and the baking powder in the baloon but I only did it with the vinegar cause it is hard with the baloon.

The problem is:....... VINEGAR STINKS, so close your nose while doing it and use the air freshener after useing it like I did (thats my instructions) :)
