the chlorine is a great oxidizer, the brake fluid (DOT 1,2,3) are mineral oil based, DOT 5 is synthetic - it will generate lots of heat and most likely burn like heck.

Or you can always do a poor mans pipe bomb - get some di-chlor or tri-chlor tablets from your pool store, fill one end of the pipe with the tablets, stick a wad of cotton down it then pour in some pipe glue and cap. You may have a few minutes but the cotton acts as you time delay, long enough for the glue to seep into the tablets. The very long molecular chains rich in double bonds and nitrogen along with the solvents make for the stuff of vandal lore!

Then again, a skipped bullet into a propane tank that has been e-vented for 5+ seconds will produce a BLEVE - boiling liquid expanding vapor explosion. The first explosion is for kicks - produces heat to ignite the secondary explosion that will create a mushroom clowd! A poor mans A-bomb for sure. Ever see a tanker car full of propane go up? Heck of a sight.

Why the heck fly planes into a building when you can ignite Delaware, Southern New Jersey, Houston and Detroit?
