Helicopter

Little kids (especially boys) seem to love trains, trucks, and other vehicles. So, when I came across instructions for this helicopter balloon, I was eager to try it out. This balloon takes two balloons - preferably one 160 (for the rotors) and one 260 (for the helicopter body.) If you only have 260s, two 260s will work just fine.

See the directions from Professor Wonder here.

 

My comments on the instructions: You will use up the entire balloon for the helicopter body. I found that I quickly ran out of "balloon" and I had to make a lot of the bubbles smaller than what the instructions called for. (For example, the 6 inch bubbles were more like 3.5-4 inch bubbles for me.)
When making the rotors, I inflated the balloon till there was 1-1.5 inches left, not the 3 indicated in the instructions. I wanted to use up as much as I could of the balloon for the rotors.

To take the pictures, I attached a piece of string to the rotors and hung up the helicopter. A helicopter belongs in the air anyway. :) For a kid's birthday party, if it fit your theme, I imagine you could hang the helicopters (and perhaps some airplanes?) around the room as decorations for a nice touch.
