Five, Four, Packet of three
As a yoof I was into model rockets, as many here seemed to be. One particularly scientific one - which actually made it into a book on the subject - squirted ink out of the nosecone as it took off, so you could examine the flow patterns over the surface after it had completed its flight.

To do this, it was in two sections, with a bag of ink between them. The thrust pushing up compressed the bag and squirted the ink out of a row of holes around the nose. Now, after much experimentation, I discovered that the perfect way to make these bags was to use the teat at the end of a condom.

All was fine until my mum discovered the left-over condoms. After explaining why I had them, I think she didn't know whether to be relieved that there was a good reason, or sad because her son was such a sad geek that he'd probably never need them otherwise...

That's ironic
because I actually put a fuse in my cock.

There is no force pushing upwards on the payload inside a rocket
The exhaust gases from the engine cause an opposite force which propels the rocket skyward.

So there is no way for the ink to compress towards the nose of the rocket. If anything, it would be drawn towards the rear of the rocket due to the acceleration.
