Hi Mr.K this is our invention! We used B’s Principal for it. We made flying shoes! The shoe has a propeler on the back and right side up wings on each side. The shoe is on a plat form that is kind of like Moon Shoes. Wheels pop out of the bottom of the shoe like rollerblades. This could be also like a stick shift car because a stick shift comes out of both the platforms. The is stick shift is the controls for this vehical/shoe. You have both hands on it and use the button to start or stop it. You have to move the stick the direction you want to go! It is powered by wind energy. We will give you a diagram tomorow at school if you want!

The invention I came up with is a plane go-cart. This follows Burnoulli’s Principle. It is designed for kids and can only be used in an open field. It is basically a miny version of an airplane but it only holds three kids. It can fly for about ony 50 meters and can go 10 feet high. I hope you enjoyed this paragraph.

Ok, so this might seem sort of wierd and pointless, but if you had a sudden desire to run fast and jump high you might want one of these. One of our inventions was running wings. They would be 20 ft. long wings that are attached to your arms. They would be made out of lightweight aluminum. By the way, there would be an iron bar connecting them behind your neck so that you don’t always have to be holding the weight of them on your arms. You would run really fast and then leap and pull a string that would deply flaps on the back of them, propelling you upward!!!!

Mr. Kremer this is my third time trying to enter my invention (the computer keeps deleting my work, so this will be short) I am still doing the car invention following Bernulli’s Principle. I may have an even cooler invetion by Tuesday though, I need to draw a diagrahm.

Steele,
Sorry about the computer trouble. Thank you for sticking to it!
Henry,
Your invention sounds just like one of Leonardo Da Vinci’s. That’s good company!

Our invention is a flying suit mechanism, following Bernoulli’s principle. There is a large structure that fits around the waist, made of lightweight aluminum. It is shaped somewhat like a propeller, with large arms that stretch out and small jets on the bottom. The original thought was to have two jet-powered shoes, but this could be uncontrollable, so the propulsion mechanism is placed closer to the center of gravity. There are also large wings that attach to the arms in order to give the user greater lift and steering capability. The user also wears a large padded suit in order to protect their skin from the wind pressure and to take the weight of the wings off their arms. They also must wear a helmet to protect their face and an air tank so that they can breathe at high altitudes.

hey…..i can’t realy explain anything, i am not good at it at all.
i will, however, give you a diagram on monday, the same day im taking the test,bye!!!!!(be nice, no bullying!!!!!)

Mr. Kremer,
My invention follows Burnoulli’s principle. It is a skateboard with a spoiler on the back like the drag racing cars we talked about in class. Since a spoiler is an upside down version of an airplane wing, then the greater pressure pushing down on the spoiler gives the skateboard better traction. I don’t really know that much about skateboarding, but I do know that people crash a lot. Hopefully this invention will limit the number of skateboarding crashes since the wheels will have better traction.

Mr. Kremer,
Jake and I mad a sort of mini airplane that follows Bernoulli’s Principle. It includes a cockpit sitting on a jet engine. There are two wings attatched to the cockpit. Each wing is curved upwards at the end. Underneath the engine is a wheel capsule with three wheels arranged in a triangular form. The wheels move in and out of the wheel capsule on the belly of plane. Above the cockpit is a spoiler to keep the “mini-plane” from losing control. There are chunks of metal to fill in the gaps so the “mini-plane” looks like a sideways cone with wings. I will bring in a picture tomorrow for the class, and I have already sent you an e-mail with the diagram.
Thanks.

Mr K, our invention is The Rollervator! It is a roller coaster and a elevator put together. You get in the single car and then using a hydraulic lift powered by Pascal’s principal it pushes you up to the top of the trac. Then you go speeding down the track, for an exciting thrill!!!!
Thanks,
Natalie and Jessica

heyy Mr. KKK
For our invention claudia and I used Pascal’s Principal. We created a hydraulic lift that lifts the car of the roller coaster up and shoots it of onto the track. There is really no point to this invention except pure fun. We hope this will increase roller coaster rides scarryness and fun.

Students,
I need more scientific detail related to how your inventions work. Please describe how they are using Pascal’s or Bernoulli’s Principle. Also, no more flying shoes or people. Let’s see some new ideas!

Hey Mr. Kremer. My invention is very complicated but ill give you my best shot at explaining it. (I really hope this isn’t something we would be able to construct ourselves.) It is a glider that is propelled into the air by hydrolics. It uses both Bunulli’s and Pascal’s principals. The hydrolics (pascal) propel it into the air with a super pressurized water chamber, a wedge, and some extendable tube. (I’ll explain it more in detail on my paper. When the hydrolic mechanism shoots it into the air the glider’s shape, and wing shape (Burnulli) make it so is keeps a stable position in the air.
How’s that for new ideas…
oh and am i supposed to explain in more detail how it works on my paper or just to u?

Hey Mr. Kremer! This is Maddie and Caroline’s invention. How many times have you ever wanted to hover on a bicycle? Never??? Well, this is the new flycycle! The flycycle is just like any normal bicycle, except, with a push of a button, the metal fins on the wheels change into paddles, once it is airborne. This follows Bernoulli’s Principle because, as Bernoulli’s Principle states: As the velocity of a fluid/object increases, the pressure exerted by that fluid/object decreases.

hello mr k.sorry im a little late posting this to the blog.
! ok, so, for my invention i had a car with four wheels. there is an unbreakable glass box where u ride in. inside of the box there is a stering wheel, and a remote control. the remote control buttons are, retract wing, expand wings, raise altitude, lower altitude, left, and right. when you expand your wings, a jet engin on the back of the transportation device turns on, allowing you to lift. Then of course you say: How does it fly? (i only put that question there because i forgot to put the answer earlier) Well, there are wings on the side of the transportation device with a lump on the front top part of them. The outside of the wing is made of iron, and the middle of the wing is hollow. the wings shape helps the transportation device to fly. That is all. I have a diagram that i presented in class already.

hey ana and i made an invention called a hover taxi…..basically, and i mean very basically, it is an egg shaped capsule that can fit anyone, mad out of stuff like what those cars were mad out of in osmosis jones with helicopter propelers on the bottom.(no driver necessary)
December 11, 2008 at 12:54 pm
OK, this is my invention. THE SPOILER CAR. It is a car in the shape of a spoiler made to go at high speeds to increase traction and therefore increasing speed. This invention follows Bernoulli’s Principle, because the air flow below the car has to travel a greater distance and fluids at a greater speed put less pressure on the object. So the net force is down!!!! Ta Da!!! Also the SPOILER CAR has an intake hole n the front so that at high speeds the high moving air makes the motor work.

My invention is a gliding device that uses a hydrolic turbo lift to launch it into the air and from there it glides…thats kinda all there is.

Hi, my invention was the foot fan. This invention uses Pascal’s princable. Just like a sewing machine you use the foot pedal to power it. When you push the pedal it pumps a breeze of air through the tube directly to your face. This is great for working because its hands free.

It’s fresh! It’s new! It’s the PRINKLE!! The Prinkle is Hope and Anjali’s invention that can be used as fun for children, or could be a way to sprinkle your plants and lawn. To opperate the Prinkle, you either step, punch, or sit up and down on a pump. That air pushes water out of the small holes in the water bucket, sprinkling water of fun! This invention represents Pascal’s Principle by exerting a small amount of pressure in a small area, cauing a larger amount of pressure in the larger area- which demonstrates equilibrium. Water squirts out of the holes. Therefore, demonstrating Pascal’s principle.

David,
I need more. Tell me how they utilize the two Principles.
