I can think of so many hilarious situations in which to use this to torment and / or freak people out with this flying sphere.  It weighs only 350 grams, 42 cm in diameter, can be made using household equipment and is about $1,400 to make.  The goal is to use for reconnaissance or rescue missions and to get in to hard to reach places where other crafts can’t.  Christmas gift?
