Science Buddies: "Ask an Expert"

Yeast only 0ml
Sugar 125ml
Sugar & salt 500 ml
Sugar and Vinegar 260 ml
Sugar and baking soda 600 ml

I just wanted to know if These results are correct and justified

Hi,

Yes, those results make sense to me - is this what you were expecting? What was your hypothesis? Seems like the gas bubbles are produced most when you have yeast plus sugar and salt. How do you explain the baking soda result?

Great project - seems like it worked well
