💥 DANGER
Will use up ALL your ram. Don't call any of the functions themselves without having kill -9 handy.

These are a collection of various ways that you can implement memory bombs in Python, along with some code to test how effective each one is.

ascii_bomb: 0.878GB
emoji_bomb: 2.000GB
while_bomb: 3.532GB
double_bomb: 3.375GB
