Paper bag invention?

Question

my daughter is in the 5th grade and she was given a brown paper bag(sandwich size) and was told to invent something, we need help on this, please anyone.

Answer 1

Put her lunch inside of it and tell the teacher it is now a supermarket in a bag.

Answer 2

decorate it and make it into a cricket house

Answer 3

ok, here's one, lets say, 'you are trying to invent a gunshot sound for a radio-play.' get a small fan, or some way of inflating it like a balloon, until finally it pops. i dunno, after all it can't be overly complex if its for fifth grade...

Answer 4

wow, uhm invent a flying car =D. pimp it out in cool colors and give it something weird idk to sstand out. good luck

Answer 5

Inflate it, and pop it! (Improvised signal call)

Tape some foil to the inside (insulated sandwich bag)

Decorate it with googly eyes and sticks for arms (a doll/puppet)

Fill it with jagged pieces of metal and tie a rope to the end of it (a flail)

If your daughter is small enough, decorate it and put it on her head (a hat)

...that's all I got.
