People everywhere duck and cover at the sound of the air raid siren's scream. I'm finished!!! Had to work through all day today but I did it! It's done! I ended up gutting the siren and mounting a electric motor from a model airplane inside. When you pull the hand lever it spins like mad and really sounds like a slightly higher pitched version of an air raid siren. The rechargeable battery is hidden in the tank. I looked everywhere for rivets, once I found the ones I wanted I tested it on a scrap piece of metal. I'm glad I did. It looked horrible. So I decided not to use them. I'm really glad I waited to test it first. If I hadn't I would have had 100 holes in the tank with nothing to fill em but these hideous rivets.
