Children love the part abzuschiesen

My nephews / nieces love the part 4-6 years
But you should pay attention to knitted discipline otherwise injured nor who ..
I've always used the bottle and pumped and all the items before sent on distance.
(The pump was too heavy for the small :-))
And nobody is allowed to touch the cord until I'm gone.
The cylinders may little fill if they are no longer like they no longer fill ;-).
Even without water it knocks the bottle extremely high ...
One can experiment a bit with bottle sizes and quantities.

Disadvantages:
- The launch pad is a little too easy when you clumsily pulling on the cord, the launch pad falls over and shoots
if it stupid expires. So complain anyway and meticulous attention to the direction of pull and pull type (short jerk) ..
- Let the children play alone so as to avoid !!

Otherwise prima ...
