Home alone with my brother all day? first answer 7pts!?!
Landon, firstly I would keep away from the kitchen, unless your getting snacks. You parents gave you a little responsibility, they don't want to have to come back and find you two in a hospital somewhere.
What you could do go through some of the topics in Yahoo Answers, and see if you can relate to some of the answers. Or you could google Nasa and see what they are up to. Even Boeing or Air Bus. Or check out General Motors latest or even mazda.com. Use the internet for some safe fun and learn from it at the same time.
at least u got PC and internet ... u can do everything...
just stay away from FIRE and don't think about cooking urself.
So you don't have to turn on the oven/stove, get some toothpicks and marshmallows and you can build stuff out of those two items.
