Got it right but second batch broke

first and third batch of macarons turned out quite ok but second batch erupted. all batches came from the same batter. difference is that the brand of baking paper used was different for the first and third batch and the baking paper used for the second batch was crumpled (not sure if that plays a part) for context, the first batch was filled with smaller macarons and subsequent batches were all normal sized. also after the second batch erupted, i decided to try splitting the third batch into two smaller batches for baking. they turned out fine after that. i’ll attach a video of the batter in another post
