crazy Louis and Mad Max strike back with the PATATOR!

we are only half crazy and built a patato gun ... have a look.

during the first test we blown out the rear extremity of the pipe... maybe the next few times, we put less deodorant gaz...
the first patato trown went on a tree.. and disintegrated. the second went further but still we have to improve ;)

the trigger seem to suffer from moisture (standart piezoelectic briquet) :(

some of our tests:

the potatoes can reach an altitude of over 80 m height while launched vertically (8s time of flight, 4 s to come down, h (t)= g t² /2)
