So, this Sunday, at church, I took part in a game. Pictures of strange inventions were put up on the screen, and us participants were than supposed to guess what they might be. One of the pictures:

Pretty impressive looking right? See, the colors reminded me of a can of toxic waste. With the stripes? Thus creating my guess:
"It's a toxic waste launcher! It shoots capsules full of toxic waste, which explode on impact (the impact being your enemy if you have good aim) and then cause skin to burn and bubble and then melt off!"
This, of course, earned me some strange looks, and the pastors response was: "No it's not a toxic waste launcher, and that's actually kind of disturbing."
It turned out to be a buoyancy gun. It shoots out capsules that expand into life saving devices when shot at the water near drowning people. Whatever. Close enough.
