How does someone with a fishroom use pvc pipe?
Baking soda is used, simply because it can release CO2 which makes tiny bubbles in the dough. (I never use soda, yeast is far better). It is also used to extinguish fires because of he CO2 released displaces oxygen so it starves the fire.
We also didn't pay $100.00+ for a pair of tennis shoes and had no designer labels on our clothes, walked to get somewhere and could go to the store with a mere quarter for candy and a soda. We had no microwave ovens so we learned to cook and had to walk across the room to change channels on the television, (there were only about 7 choices, though). We did homework without being told too, and if we got in trouble at school, that was nothing compared to when our parents found out about it! I do worry about the future of our world and how the generations to come will cope with hardships since life has become so coddling.
