I'm sitting for two of my cousins who are both in about 5th or 6th grade, and they just came up to my room and asked me to come see what they've been doing out in the shed.
Well, it turns out that they've been hooking up old computers, and they've got some of those white icicle lights strung up so they can see, and they've fixed an old TV! They told me they're planning on fixing a printer next. I wouldn't be surprised if they've figured out how to splice the cable and hook up that TV by dinner time!
I think it's some pretty amazing stuff for two kids to be up to!
