Here's a brotli file I created that's 81MB compressed and 100TB uncomrpessed[1] (bomb.br). That's a 1.2M:1 compression ratio (higher than any other brotli ratio I see mentioned online).
There's also a script in that directory that allows you to create files of whatever size you want (hovering around that same compression ratio). You can even use it to embed secret messages in the brotli (compressed or uncompressed). There's also a python script there that will serve it with the right header. Note that for Firefox it needs to be hosted on https, because Firefox only supports brotli over https.
Back when I created it, it would crash the entire browser of ESR Firefox, crash the tab of Chrome, and would lead to a perpetually loading page in regular Firefox.
