Made out of a bicicle pump! The idea is to use the one way valve that every bicicle pump has on its piston, to improve the performance of the gun, instead of using loose pistons as usually. I know the difference may not be crucial but it's for the sake of well-design. The piston is too heavy but seems to prove the theory. At only 75psi it shoots a 0,2g 6mm plastic bb through a steel (yes, steel. This is Europe) coke can. Filled with water it pierces the can and leaves a mark on the other wall. Air leak detected, soon to be fixed. UPDATE 20150719 Air leak was fixed with teflon tape. Cannon was intended to be tested to 10bar / 145psi. At 8bar / 116psi the back bursted off the main body, propelling it against a wall, with the cannon hitting at a great speed. Result is a bent cannon. Speed doesn't seem to have decreased but precision has been seriously affected. Plans for now are to test the energy at 75psi (like this teaser shows), then cut the cannon to the unbent part (which is about half the lenght), glue the back permanently and test energy again at 75psi to see the relationship between cannon lenglt and muzzle energy. Afterwards, with the back end fully glued, repeat tests at 116psi / 8bar and hopefully get the same energy as full-lenght-cannon @ 75psi. If not, test pressure until total burst, or the desired energy achieved. Advise is greatly appreciated. Thanks for watching! A FewFriendsFace production Likeyright FFF2015 All likes reserved

Ad Andrea piace giocare a tennis. Si infervora proprio mentre lancia le sue “cannonate”. Lo scaricano, dice. Io ho preso lezioni di tennis per tanti anni, ma non è mai scattata la stessa ardente passione, anzi è uno sport che mi ha sempre annoiata. Però a lui piace e non abbiamo mai giocato insieme, perciò va bene. Giochiamo. Ci scaldiamo, due palleggi, poi partita. 0-15 per lui 0-30 per lui Poi rimonto Poi pareggio Vantaggi Punto suo. Il game successivo vinco io, poi di nuovo lui. Insomma all’apparenza è una situazione come tante altre. Ogni tanto gli arriva la palla giusta e tira la sua famosa cannonata. Io ero già piena alla partita n.2, ma lui gioca a un metro da terra. Corre, salta, recupera le palle, tira, sbaglia, ritira, simula il punto decisivo, insomma il pacchetto completo. E io penso che ognuno di noi trova la sua dimensione con qualche attività. Per me sono terapeutiche quelle ripetitive in cui disattivi il cervello e macini chilometri, per lui sport come il tennis. Allora va bene, ancora una palla, e poi un’altra. Ma quel palleggio è finito con la palla a rete e non si può mica finire così, allora un’altro giro ancora. Perché camminare insieme significa anche questo. Giocare a tennis quando non ne avrei mezza. Perché so che a te piace. E questo a me piace. C.
