I made this for my 7 year old son. It only took 30 minutes to make but was a smash hit wherever he went with this costume.
Hoe I made: Roll news papers into a size of a head and wrap it with a plasic bag. Tape a stick pn the head-ball, cover with a cloth, put a mask from the top. Make another one and hold each on your hnd. Move them up and down, twist and float as they are real. ( In the center is a person covered in the same cloth with the mask on…just added some make up on.)
You can replace with any kind of mask. They were creepy and looked like the two ghost were really floating in the air.
