Balloon-Powered Flying Saucer

What if you are an alien, on your way to planet earth for some research, and your flying saucer is suddenly out of fuel? This smart guy who had just been to a party had an answer: balloons! 

This set consists of 151 parts. All parts are official lego parts and they are all available in the colours shown in the set.

The red belt is not attached to anything, but held on his place by the upper and lower part of the flying saucer, so it is unable to move or fall apart. The upper and lower part of the flying saucer are attached to each other by bricks with studs on 2 sides.

This set was designed and creatied by my 14-year old son.
