Hiya , does anyone know how to correctly use a parachute kite ?

I assume you are talking about a 'square' (ram air) type.\n\nBasically you will need to pull it to get the ribs inflated then keep it orientated into the wind (should do that itself). Pulling the risers gently should cause it to dip ... too much and it will (like a real one) wrap itself up.\n\nEnjoy.

You can control the direction of the kite much better with 4 lines than with one.

Increase the drag, or resistance by enlarging the surface area. The parachute is a simple solution. \n\nHave you thought of making a whirly-bird/helicopter-type device to slow down the fall of the egg? Balsa wood angled correctly should be able to produce simple a rotary blade that would slow down the decent of your egg. Keep me informed.

well hopefully this helps:\n\nif you want to do it moving i suggest to go with the wind. try the first part of the trick lifting one part of the board, with all your weight and balancing then do the following  1.   bend down on your knees( with right foot on about middle of the board, and the other in the tip of the board.), 2.   lean to your left side(if thats the foot you push with, with your left foot) and press the board and once the board is up lean to the other side while sliding your foot the other way so the oppostie side comes up as well\n\n there short and sweet, for you\n\ncome to HELP YOU, first practice it alot of times. make sure you lean tothe other side WHILE you slide your foot.\n\nTip: I would try it in the grass first)\nPS it works, but it will take some practice!

I tried to break the law of gravity with a kite on a dare when I was a kid. I broke my leg.

Lizz –\nMost kites are designed for a specific range of wind velocities.  If your kite doesn’t list a range, then it usual default is 5 to 15 mph, especially for diamond shaped (the kind with a tail) or delta wing types.  Box kites need more wind.\nOnly the lightest kites and best flyers can usually get a kite up in a 2 mph wind.  I have flown kites in ranges from 2 to perhaps 35 mph.\nFor 5 mph (steady, with gusts up to 10 mph) most novices can get one up and keep it flying.\n7 mph is usually very easy, 10 isn’t bad.\nSimple kites have a single location to fix the kite string to the kite.  Better kites have ways of adjusting the “bridle” which changes the “tilt” of the kite toward the wind.  This allows them to be flown in a wider range of wind speeds.\nAll of the speeds mentioned above are “ground speeds,” that is the velocity of the wind at ground level.  Keep in mind that the weather report wind speeds are usually not recorded at ground level, so take them as a rough guide.  Also be aware that depending upon where you fly the kite, the difference in velocity only 100 feet up can make a real difference.  Some kites might be hard to get off the ground, but then soar like crazy once they get up.  You will need to experiment.

You will not be able to sail that boat using tradition sailing methods.  But if you wanted to harnass the wind to go downwind only, you may want to try using a surf kite to tow you.

Cool.\n\nUse the FOIL method. First, outside, inside, and last.

first u have to know where to hold the paddle first. \nhold out your two hands(while holding the paddle)to the front. \nthen bring it over your head, and put the paddle along ur shoulder blade, behind ur neck.\nhold on to the paddle while making sure the insides of ur elbow is in 90degrees angle.\nthats the position to put ur hands.\nget it??\n\nto paddle, just swing the paddle..\nu should make sure that ur hands are straight the whole time.\nthen just ram the left side into the water, pull to the back, twist the paddle, ram to the right, pull back , twist, lalala.\n\ni hope i make sense.\nget someone that really knows to actually SHOW you.\n\ngluck.

Hi Jeric!\nHere is my explanation.\nLet’s consider the simplest kite construction – a triangular plane of light but rigid material, the tail attached to the kite as well as the rope help you to keep the kite in stability - to prevent the kite from ducking and spinning. The best weather to fly a kite is the evenly blowing wind with no gusts. Now let the kite be in normal position for any flying kite that is making an angle u to horizon. A mass of air m at velocity v1 has momentum M1=m*v1 – this is a vector. When it hits the kite’s underneath it reflects from triangular plane changing its direction to v2. Thus M2=m*v2. The change in momentum through time t will induce force F=(M2-M1)/t acting on the kite from underneath. Vector F has two components: Fx - horizontal one, Fy – vertical one.\nFx=abs(F)*sin(u) which is compensated by your hand through the rope, otherwise the kite would be carried away with the wind. Fy=abs(F)*cos(u) is the force that compensates the gravity force on the whole construction + that hoisting the kite until the length of the rope permits further hoisting.\nThere is another explanation in terms of aerodynamics, but mine will also do. Flying kites is a healthy sports!

The simple answer is to have a mechanism for absorbing the impact of the fall. What to build depends on what materials you are restricted to.\n\nThere are several ways to go about it. Design a super-structure (the outside part) that crumples when hit. Suspending the egg is also a great idea (as was already suggested) If you can't or don't want to use a sock or stocking, using some kind of thick substance like gelatin would work well. Parachutes also work very nicely, I've seen some cool ones that worked like helicopters, spinning to slow down the descent. If you want a better answer I suggest posting whether you are restricted to certain materials.

It's a pretty simple project. It's a car about the size of a matchbox car. But it's made out of lighter materials like wood or plastic. With a holes bored through the center in the shape of an "L" When the balloon is filled with air and released, the car moves forward by jet power from the escaping air. \n\nBasic directions: make or buy a small matchbox sized car made from plastic or wood. You can either drill two holes to form an "L" shaped passageway in the center of the car, or you can hollow out the car and glue small tubes inside it to make the "L" shaped passageway. Of course, you'll also have to put a small chimney with a lip on the top of the car; this holds the balloon in place. So, the balloon sits on top of the car. The jet exhaust points out the back.  Blow into the exhaust hole on the back of the car to blow up the balloon. Put your finger over the hole to keep the air in. Set car on the floor and release. As long as there are no leaks and the car's wheels spin freely, it should work fine. The lighter the car the faster it will go. The bigger the car, the more stable it will be. \n\nYou can try getting a pinewood derby kit from the local cub scout's supply store. However, you should replace the pine body with balsa wood. It's lighter. \nGood luck.

Panda Ninja: say something smart dont be a smart a** maybe she is just starting out u moron.\n\nTo ollie u place ur front foot in the middle of the board, and ur back foot on the tip of the back of the board. Now try and pop the tail which means put ur weight on the tail but try and jump with ur other foot at the same time.then push ur front foot to the top to level ur board. Once u get it ride away with a smile.

When I was in 8th grade, we had a similar project, but we were only allowed to use straws and tape. Out of about 60 kids, only 2 didn't break. Mine was one of them.\n\nIt's hard to describe my design, but I will give you a few tips. \n\nThe most common reason that the other designs failed was because the egg fell out of the device. For a holder, I took about 10 straws in a bundle and taped the ends together. The egg went in the middle of this bundle. Whatever you do, make sure the egg will not fall out of the holder when it is shook or turned upside down.\n\nThe rest of the design was a bunch of straws folded into a triangle shape taped to the holder. Triangles are one of the strongest basic structures. \n\nHowever, since you are allowed to make parachutes, I would almost certainly integrate that into the design if I had to do it again.\n\nAlso, test your design at home before bringing it to class. This will allow you to fix anything that doesn't work like you expect.
