Here is my theory of how to tip the iceburg:
1: turn dark blue, light blue, or aqua. light blue is reccomended 
2: Now go to the biggest part of the iceburg (that big chunk at the top)
3: Dance or something!
4: the iceburg might tip!!!!!
i hope that helped

It’s actually impossible for the iceberg to tip. It has something to do with its HTML code, I think.
yea but if it could happen this would most likely be the wayto do it
