A little water and compressed air can be a lot of fun. Especially when photographing from a distance :)
I managed to get a lot of now-you-see-it-now-you-don’t photo sets through the course of the bottle-rocket session, so I was very happy to get this one where the bottle was still visible after launch. A couple of launches later one of the bottles exploded, breaking the compressor nozzle and putting an end to the fun.
