Yet another poor quality video of the homemade pneumatic cannon made out of a cheap air pump for using the own piston as it works like a one way valve. Thus, you don't need to leave a small clearance for air to leak and load the main chamber. The piston let's the air flow into it, but on the shooting phase it blocks it. It's the same that happens when you pull the handle of the airpump (air enters the cylinder) and then you push it (air is NOT released, but compressed). The target in this video is the back plate of a pringles can. At 3,5-4 atm as seen here it pierces it. At 6 it goes through. At 7,5 the rear cap explodes XD And no... I'm not in undies. It's a swimming pant (summer in Spain!!) XD So please focus on the ballistics and keep YOUR mating rituals for your friends and beloved ones. Another funny fact. The rear cap explossion propelled the main body against a furniture and the aluminum cannon BENT. So poor accuracy now, but back before the accident it was kinda good...like let's say hit an apple at 15 meters (yeah, I know but I didn't want to put my eye or face close to the gun, so it surely would have been better. To the naked eye, the BB looked like flying pretty straight) Thks4watching All likes reserved
In this video, we explore a powerful cultural crossroads as Poppy joins the villagers of Papua New Guinea in singing Christian religious music. Though this music is not native to their culture, it has become an integral part of their spiritual life—introduced by missionaries and embraced by the community. The contrast between the villagers’ traditional ways and these newly adopted songs creates a unique and emotional experience, highlighting the deep connection between faith, culture, and music.

Quand vous naviguez à la voile, le vent que vous ressentez à bord n’est pas le vent réel : c’est le vent apparent Aux allures portantes (vent venant de l’arrière), la vitesse du bateau « rattrape » une partie du vent. Le vent apparent est donc plus faible : on soustrait la vitesse du bateau à celle du vent. Aux allures de près (vent venant de face), la vitesse du bateau s’ajoute au vent rencontré. Le vent apparent est alors plus fort : on additionne les deux vitesses. Comprendre cette différence est essentiel pour bien régler ses voiles et mieux comprendre le comportement du bateau. ⛵️ Vous débutez en voile ? Nous avons créé une formation en ligne qui explique simplement toutes les bases de la navigation, avec des exemples concrets et faciles à comprendre. Le lien est dans la bio ⬇️
