Haunted Balloon

 A haunted helium balloon for Halloween (or any other time of the year!) This can really scare you, if you aren't careful!

You need:
one Helium Balloon (on ribbon or string)
one wrapping paper "ghost" (this is the ballast)
  

Step 1 Unweight

 When you get a balloon, it usually has a weight on the end of the ribbon, to keep it from floating away. (pic 1a) Some times these are plaster, or a bag filled with either sand or beans. For our purpose, this is too much weight, as we want the balloon to float in an eerie manner. To facilitate this, replace the weight with a "ghost" made of paper. (pics 1b & 1c) Roll up a small ball of paper to put inside another small sheet of paper, to make a ghost. Tie him onto the ribbon.

So basically, you trim for neutral buoyancy and it follows any available air currents. That is VERY cool, well done.

Ah, trim for neutral buoyancy! I knew I lacked some jargon. Exactly! I love watching the balloon move ever so slowly across the room! Maybe this needs a little basket? gondola? HO scale ballooning! Hmmm... Thank you very much!
