To look a bit thinner, we suck our stomachs in. The thing I don't get is where everything goes- does it move upwards or does everything get compressed?
At school we have been learning about metals reacting with acid. I had a look at the periodic table and I saw that pottasium (K) was an alkali metal. I also knew that bananas are an excellent source of pottasium. So why, when I eat a banana, does the hydrochloric acid in my stomach not react and make me explode?
