If you stand back it wont hurt you. Also again I wont guarantee it will fly but it is still cool to watch.

Cool!I never thought of using a engine to propel a bottle.

I rather think that thirst thing that happens is that the rocket motor comes loose and rattles around inside the bottle, melting it and igniting the goo.

The whole mess will probably bounce randomly around the ground, spraying burning plastic all over the bystanders.

Or am I just being pessimistic?

What's holding the rocket-motor in? This looks like it may be rather unpredictable in flight... L
