Just in case you were wondering, Kirsten asked the same thing! Do you think it’s the right answer?
as a scientist could you explain why the middle of the top rises more than the sides? yes you are officially the only scientist i know ^^

The quick & dirty answer is this ;D –>
Because the sides are in direct contact with the metal (hooray for good conductors), they tend to cook quickly. This doesn’t allow time for chemical reactions to occur completely. As compared to the happy middle where more CO2 chemical happiness is made because the heat cooks it more slowly.
Hope that’s what you were looking for. YAY you called me a scientist ❤ !!!
