This was from the history channel's weird weapons (WW2) series and I found it very interesting. We were going to give bats miniature time fuzed napalm grenades and then drop huge numbers of them over japanese cities in broad daylight so they would look for attics, eaves and overhangs to hide in. We know it would have worked because some of the test bats escaped before they did a full test and burned a bunch of buildings down at the military base where they were doing the development.

Some genius figured out that if you mix sawdust and water, then freeze it you get bulletproof ice that doesn't melt quickly. They were going to make an island sized aircraft carrier with an on board refer plant to tow out into the north atlantic and bomb Germany from.
When they were demonstrating the strength of this new wonder material they shot a block of it with a revolver and the bullet ricocheted back and hit one of the admirals who was present in the leg.
