Wha?!?!

So today at the bunnies only party I found out that the drum can break and you will earn rares. And this is what I was like.

 

So we hopped for a while with about 40 people. But it didn't break. The girl then said it would break with 100 people, so it's a mystery. If you have seen it break or helped it break before comment so we can solve this mystery!
