How does one make a Zip bomb?

Question

This question about zip bombs naturally led me to the Wikipedia page on the topic. The article mentions an example of a 45.1 kb zip file that decompresses to 1.3 exabytes.

Answer 1

All file compression algorithms rely on the entropy of the information to be compressed. Theoretically you can compress a stream of 0's or 1's, and if it's long enough, it will compress very well.

That's the theory part. The practical part has already been pointed out by others.
