Chem Experiment Assistance

Hello. I attempted to do the experiment which I have seen many times where sulfuric acid reacts with sugar and makes a black solid and some smoke. We used about 4M H2SO4 which we got from a car battery, and the reaction did not work. Next we added Baking Soda to the mix in order to see if that would do anything.

When adding the baking Soda I hypothesized that it would bubble and maybe bubble on bottom causing the gas to try to escape and make it puff up some, but instead it created a white sticky foam which was still acidic.

I wanted to ask if anybody knew what could have gone wrong with the initial reaction, and if anybody knew what the white foam may have been.
