Dan and Steven rocketeers

Tomorrow is flashpoint and it is always very very important to reherse beforehand.  Tomorrow we are doing water rockets.  So this morning, dug out the gear.  Went to CBC bearings at Archerfield where the very helpful man put up with my PVC conduit and coke bottle on hos counter while we went through his O rings to find the correct size.  Ended up with 16x2 and 17x2.  Then looked across  the road and watched a couple of helicopters take off.  Then home and we have been bombarding the neighbours ever since.  Neighbour Cory very kindly saved me from having to purchasse and consume several lites of coke.

It's about to blow.
But do you think I could catch a shot just as it lifts off?
