The 2x2 liter bottle.

The 2x2 liter bottle refuses to take off. It seems that there are leaks in it :-( One advantage though: it's very easy to decompress these bottles: just unscrew the cap on top (taking care that the thing doesn't launch unexpectedly of course!).

The water in the still filled 2x2 liter bottle is poured into the 2x1.5 liter one.

You can see some bad looking bubbles in the tape. And yes, this one leaks also and refuses to take off.

The last 2x1.5 liter bottle. This is the one we first put silicone in, and later filled up with glue too ...

... but still leaks! At least, this one does want to take off.

Ready for launch ...

The rocket flies in a rather curved path and rotates about its axis. A bit disappointing, I hoped it would lift off more vertically ...
