This is an oldie, and I guess probably originated as a variation on the wind up elastic planes.

It's fairly simple, and a great one to do with kids.

Materials you will need are:

*2no bottles (I used one 500ml for the propeller, and one 600ml for the body, but you could experiment with different sizes and shapes)
*3no elastic bands
*2no paper clips
*1no piece of wood about 150mm long (maybe an old broken ruler? I ended up using 2 plant markers)
*1no bead

Tools you will need:

*knife or scissors (I used a combination of both)
*drill or some sort of punch (I used a 2mm drill bit)
*long piece of hooked wire (coat hanger?)
*random tools for bending the body paper clip (you'll see!)

I did this for my two year old son to play with in the bathtub. I used six rubber bands between the nose and the prop, but it spun the bottle because my "wings" were too short and I used a very buoyant wood. I work in a metal fab shop, so I'm going to try making him a longer wing from a thin ga. metal tomorrow. Overall a fun idea, mine just needs a few tweaks.

Multiple elastic bands is a good idea. Making the wings wider should help as well as making them longer.

I couldn't find a drill so I used some kind of geometry tool heated on a candle.
Anyways it's cool so I voted for it in the toy contest

Good idea. A heated wire might be a good way to cut the propeller as well. Would make nice neat cuts through the thick plastic.

Obviously without burning yourself!!!

Embedded. Thanks, that was easier than I thought it was going to be.

Thanks, I didn't realise you could do that. I will have to give it try...
