A hypothesis in my own words is a basic idea of what YOU think will happen during your test. So, it could be wrong or be right, you won't know until you test it to find out, or unless you're proven wrong or right while doing your test.
My hypothesis is If you mix baking soda with lemon juice and vinegar in a bottle and put a balloon over it, it will inflate the balloon faster than it would if you put hot sauce instead of lemon juice.
