Make a Fireball Shooter

Another great video from the Internet legend KipKay. Wow, I really want to do this because not only does it look fun but, it's simple and cheap. I just need to find a store around that sells flash paper and cotton.

Guy Builds His Own Jet Fighter

When Arthur van Poppel found some online plans on how to build a jet fighter he took them pretty seriously. He actually built the thing! While his homemade jet won't ever take flight he can actually drive it. The jet has a scaled down version of the real thing and has collapsible wings so that he can fit it in tight spaces.



"Apart from a crafty piece of machinery, the Jet Fighter is especially some spectacular entertainment, full of surprises! In the cockpit, one finds sound equipment and a monitor with surveillance cameras. Apart from this, the Jet Fighter has many sound effects and visual entertainment, such as smoke-, water- and confetti-effects, to surprise its audience again and again. These effects can also be controlled from a distance. The spectators will be amazed!"

Turbocharged PC Cooling

If you have ever seen an ad for a "turbo charged", super speed pc than you'll think of a much more litteral meaning whenever you see one from now on. Mark Purney constantly saw many of those ads and finaly decided to do something about it, make his own REAL turbocharged pc. While the thing isn't actualy turbo charged it does use a real turbocharger from an old 90's Mitsubishi Eclipse and uses it to cool down the system. The turbocharger doesn't run at anywhere near max rpm because it is meant to be water-cooled and Mark doesn't want to make the thing any more inpracticle than it already is. He says that he uses it every once and a while for a little fun throughout the day and to show it off to friends but, he uses a regular pc for any daily usage.

Homemade RC Airsoft Turret

Invent Geek has built their very own remote controlled airsoft turret that it made using parts salvaged from an old airsoft gun, some servos, plexiglass, and some hardware. It shoots 1500 rounds per minute and can hold tens of thousands of bb's. Their website has step-by-step instructions but don't plan on making one unless you have about $200.00 to burn. Below you can see the turret in action.

Weed Wacker Blender

If you think that you have a nice blender you may want to rethink that. Brett decided that he'd try to find a use for his old weed wacker engine from when he was a kid and he sure did! He took the engine and used it to power a blender, but that's not all. He is a huge drag racing fan and created his own miniature starting lights (christmas tree) as well as a nice looking RPM gauge and a cool trigger to power the speed as well as a cool LCD display. His favorite part.... The fact that he gets crouds to walk away from the drag race just to see his blender.

Sawdust Air Cannon Explosion

Sawdust Cannon. from Ben Stone on Vimeo.

(Above) This is the original sawdust air cannon from Ben Stone. (Below) The Mythbusters tested the great air cannon out to see if it was really possible or if there were some other things in the cannon besides sawdust.


I was a little sceptical at first until I saw the Mythbusters confirm the myth... What a great idea!

Animatronic Pumpkin Head Monster

This is an animatronic pumpkin head monster created by Woddy, a self taught animatronics expert. Woddy even made the local news with his creation. You can view his Youtube page for even more videos of his monster before and after it was completed.

What a 100,000 amp Capacitor Bank Does to a Quarter

This is unlike many other hacks on this website due to the fact that you can't do it at home..... well, unless you have access to a 100,000 amp capacitor bank

James Bond Style Exploding Pen

I just bought a shocking pen, like those novelty ones that you use to shock people, and had a great thought go through my head. I saw that when you click the button that shocks you it makes a constant spark inside of the pen. That spark would probably be hot enough to light the fuse of a firecracker. So I would cover the metalic part at the end with a peice of rubber so that you won't get shocked when you press it, then place the fuse near the area of the spark, then empty the powder from the firecracker and pour it into the pen and put enough in so that the fuse could reach it. Obviously, i wouldn't give this pen to anyone but, it would be cool to be able to say that I made it. I would test it by placing it on the ground and by pressing the button with a long stick. I will post a link to the final result once I finish it!

POTATO Cannon!

This is a cool thing that I saw my neighbors use one. It is AMAZING and can be built for less than $25.00 (It's way worth the money). There are also some videos on Youtube that will help you understand how to build this if this isn't sufficient enough.

Assembly:
Get all your parts ready for assembly.
Cut all your pipes to the correct length using a saw.
Glue the end cap holder onto the end combustion chamber pipe (Fatter, shorter one) Make sure you don't get glue into the threads.
Take the 3" to 1.5" reducer and glue the 3" end to the other side of the combustion chamber.
Glue the barrel to the other end of the reducer.
Put two 3-inch nails into the 3" section on either side so there about 1 cm apart.
Put small alligator clips on the leads to your BBQ sparker.
Let it dry for a day, then you're ready to fire.

Loading:
Ensure a tight seal around the projectile. This prevents the combustion gasses from escaping around the projectile instead of pushing it forward and will result in inefficient shots.
Cut each potato in half and put it on a board or hard ground. Use the barrel as a cookie-cutter to force a perfect circle of potato into the muzzle and force it down with a ramrod.

Firing:
Open the end cap.
Spray propellant (almost all hairspray will do) inside the chamber and close end cap tightly. Seven seconds of spraying is plenty.
Connect the alligator clips to the nails in the chamber.
Aim away from all people and click the sparker (it may take a few sparks so don't be discouraged if it doesn't work).
