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

Modern, Luxurious and Performance Our new A34 will take in the catamaran range a special place thanks to its design and the preliminary study that was carried out by the couple of our STGI / Aventura shipyard and Samer Laster architect. Designed for performance, with low draft and exact width to explore new areas, the lines are resolutely fluid and tight with important glass surfaces openings and amenities that give pride of place to space and comfort. Elegance and confort The interiors arrangements would satisfy the most advised sailors with a full and spacious navigation area, easy circulation, a kitchen with a large work surface and lots of storage space. The cabins are spacious, well ventilated and offer all the comfort on board. The decoration is neat and luxurious with warm tones, high-end materials carefully made. The Aventura 34 will be your perfect companion for your future cruises and explorations. For more info visit https://coralyboats.com
