A vacuum cleaner spaceship is easy to made. First, remove the inner parts (motor and electric stuff). You will need the case. For the wings, I used cassette decks from a stereo in one ship and parfurm caps in the other. For the tail, I attached toys pieces. Use the plastic trash you want! Personalize your spaceships! Even I made gaitling guns with deodorant caps and markers tubes. Paint using spray paint.
Now, you have a toy your kids will enjoy!
