Air pump for water rockets
Cheap pumps fail early. So I got myself a really nice pump from SKS (search for "Rennkompressoren").

The pump with pressure hose (8 meters) attached. It could be even longer - it is always good to be FAR AWAY from an exploding bottle, what never has happened so far. |

Nice, this barometer, isn't it? With a body weight of 80 kg you get 14
bar, that's 200 psi, out of this pump, with "dynamic" pumping even more.
The pump is rated up to 16 bar.
I generally stop pumping at 10 bar. |
