I don't know about you, but I am the worst pumpkin carver ever! I can barely do the basic triangles and my kids get so frustrated with me about it. Some people are very skilled and creative pumpkin carvers and can do so many cool and creative things to bring their jack-o-lantern to life. I can't because I am a pumpkin carving tool!

Leave it to a rocket scientist to come up with the greatest Halloween costume - and all you have to do is download an app. Mark Rober is a NASA engineer who created a costume last year using two iPads to create a hole in his stomach. He put a video for the costume on YouTube that was seen by more than 3 million people.
