Red Sailboat, free sailing Bought second hand in awful condition, restored and put to good use. It came with cotton sails, albeit cut with scissors for reasons unknown (!) Also no boom and no joint to have one. Sails were sewn back, boom was added but somwhow it was too heavy. Leaned too much, cotton caught water and boat capsized. Luckily I found a fiberglass rod from a broken umbrella, and some synthetic fabric for some new sails. This is the first run, tethered

Anfisbena is my first plywood boomerang Inspired by Pierre Kutek's carbon boomerang "Kayabonga 2" 2'5mm plywood, spray painted Amphisbaena is a mitological creature consisting of a snake with a head on each end. The project started as a gift for a left handed amateur thrower (this is indeed version 3 of the project) and I loved the design so much that I had to make one for myself. Tuned to almost zero wind How do you like it? :)

Telekinesis (by means of a ring of air)

I can't really think of a reason why the piston returns to the original position!! any ideas?? I made a transparent QEV coaxial cannon out of the preform of a bottle. This was inspired by a Nighthawkinlight's project, although I added a transparent barrel and had to make everything work with a wooden piston and o-ring seal. The breech seal is just a piece of rubber from the inner tube of a bike tire. Thanks for watching!

Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). 1/8th speed (15fps) and improved video performance because somehow Youtube cropped the last frames of the other videos (?) I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

The toy had a propeller (sort of like an outboard) and was powered by a wind up motor. Now it's got a sail and is powered by a wind ahoy breeze! :D

Another shot of the Rokit water rocket. This time in slomo! Full time travel achieved right after the take off probably due to the rocket breaking the speed of light. Some friends disagree with this..

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

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

On 12th januar 2015 the new HM830 takes test flights to compare with its twin 8broken and repaired) brother. Now that I achieved some experience with the older one, flying should be easy right? Well, it was, but as always, holding the camera and controlling is not easy at all!! Average flight times passed 2 minutes, promised!! This is the best of the three videos, but unluckily the wind was kinda high and I couldn't make this guy return to me so I had to cut the engine...but "he" wasn't doing it bad, huh? =)

Well, it was, but as always, holding the camera and controlling is not easy at all!! Average flight times passed 2 minutes, promised!! This time we see a really short flight. It dives, making me think it's gonna crash but then throttle up it comes back up, nose too high, airspeed goes down to zero and here we have a stall :S
