Trap for Bad Guys

I think the boys have been watching way too much Scooby Doo! Saturday night Matthew told me he was going to set a trap so that if bad guys tried to get into our house, they couldn't. So, this is what he came up with (see above picture).  I'm not sure how well you can see it but he took some cheap kite string and tied it to the blinds, across the front door, and to the base of the clock next to the door.  What a cute little guy Matthew is!  I'm sure his plan will work!
