Has anyone got a simple idea for a gumball machine costume?

Found this, looks pretty simple Gumball Machine - Take 1 bag multicolored balloons, 1 clear trash bag, and a baseball cap. Blow up the balloons. Be sure to cut two holes in the bottom of the bag for your legs and two on the sides for your arms - not big enough for the balloons to escape from. Step into the bag and secure it at the neck with ribbon or twin or pin it to your shirt underneath. Add the balloons. Now get a piece of paper or cardboard and write 5 cents or other monetary amount of your choice and stick the paper onto the hat. Viola. Gumball machine.

Well, for the gumball part, you could get lots of different colored nerf balls and put them all over her head and some on her face...leaving her eyes, nose, and mouth empty....attach them with that stuff you get a sewing stores so they will stay put. Then you could get two pieces of foam board for front and back. Color and cut out the rest of the machine and strap it on her with cord...hope you know what I mean.

The person above me pretty much had the best idea. I actually knew someone who used the same idea and the outfit came out looking really cute. It's not that hard to do, just fallow the directions the above person gave. Good luck!
