Pushing the cork into the bottle.

Connecting the valve to the bicycle hose ...

... which is connected in turn to the pump.

To the left of the yellow car, you can see Pieter, waiting for the launch.

And this launch does not go as expected! It turns out that one nail stayed in place, so the bottle launched not exactly straight upwards ...

... but hits Jans arm before continuing its erratic flight.

This time, we learnt our lesson. Both nails were pulled out nicely this time, but the rocket refused to take off!

Jan is suddenly very anxious to keep his face away from the launcher, even before the launch.
This 2 liter bottle launched very nicely; we did two successful launches.
