My images:
Findings:
Balloon 1
( 3 tsp baking soda, ½ cup vinegar)
|
Balloon 2
( 3 tsp salt, ½ cup soda)
| ||
Balloon Size (cm)
| 23cm | 5cm | |
Bubbles
(small, medium, large) | medium | small |
The balloon expanded into 23cm and the other balloon expanded into 5cm.
when the baking soda hit the vinegar it reacts and it fizzes.
I also have done an experiment that is similar to this.
