Cold Air Balloon

 Cold Air Balloon

Today we were learning about 

When vinegar and baking soda mix, an endothermic reaction occurs. This produces carbon dioxide which inflates the balloon. The endothermic chemical reaction will also lower the temperature in the area surrounding the vinegar and baking soda so significantly that you will be able to easily notice the change in temperature. it can go so cold it that it damages the bottle

Part.2. when we put the baking soda in the balloon and the vinegar in the bottle we put the balloon on top of it and let the baking soda come out the balloon ripped we did it again and it ripped and overflowed

Balloon Madness

Balloon Madness

 So we were learning about the 3rd law of physics by...

Getting an very long string and an inch long paper straw and masking tape and the last thing an balloon.

We had an group of 3 and one person blow up the balloon as the others would hold the ends of the string.The person that wasn't holding the string would put the paper straw onto the string and tape the balloon to it and blow up the balloon and let it... GOOO!! the balloons were going fast slow side to side up and down it was crazy fun doing it
